-/*
- * V5.4 - 9.1.2018 - na titulni stranku pridan duvod, proc je spusteny konfiguracni AP. Usnadni to diagnostiku pripadu, kdy se ESP nechce pripojit k AP.
- *
- * V5.3 - 8.12.2017 - prepracovano presmerovani v Captive portalu, DEBUG_MSG makro upraveno na posledni pouzivanou verzi, scitani retezcu prepracovano na .concat. Pripsany Informace o modulu, reakce na Reset
- *
- * V5.2 - 20.4.2017 - Pokud je pouzite v timeoutu EC_DONT_RUN_CONFIGAP tak se vracime okamzite a necekame na pripojeni k WiFi (take nevolame zadnou callback metodu).
- * 					  Navratovy kod je pak WCR_CONFIGAP_NOT_STARTED .
- *
- * V5.1 - 3.4.2017  - Webove rozhrani upravene pro snadnejsi ovladani na telefonu/tabletu, sila signalu AP zobrazena jako barevne odliseny indikator.
- *
- * V5.0 - 29.10.2016- Vyuziti vlastnosti ESP, ktere si uklada wifi konfiguraci do sve vlastni flash oblasti, takze nemusim vse konfigurovat znovu po startu - doufam, ze se tim zrychli asociace s AP
- * 					  kvuli bateriove napajenym pristrojum.
- *
- * V4.7 - 30.8.2016 - Metody .begin se nyni vraci s wificonfigresult_t (podarilo se pripojit k AP, nepodarilo se pripojit a vyprsel timeout pro konfiguracni AP, nepodarilo se pripojit, ale je zakazane spousteni konfiguracniho AP).
- *					  ESP NYNI NENI RESETOVAN PO VYPRSENI TIMEOUTU!!!! Je to kvuli bateriovym cidlum a DeepSleep rezimu v situaci, kdy zmizi AP, ke kteremu se bezne pripojujeme
- *					  Odstraneno odesilani reakce na generate_204 (viz. https://github.com/tzapu/WiFiManager/issues/114)
- *					  Zbytek MAC adresy v pripadnem SSID je nyni vzdy velkymi pismeny (UAA Unique Address Assignment)
- *					  Kvalita signalu jednotlivych AP je nyni uvadena v % namisto uzivatelum nic nerikajicich -dBm
- *					  Pokud do polozky timeout v .begin() metode zadame hodnotu WC_DONT_RUN_CONFIGAP, tak i po neuspesnem pokusu o pripojeni do site NENI spusteny konfiguracni AP (bateriove pristroje, stale bezici pristroje)
- *
- * V4.6 - 26.7.2016 - Moznost nastavit cislo kanalu pro rezim AP, nove eye-candy rozhrani.
- *
- * V4.5 - 20.7.2016 - Moznost konfigurovat cislo kanalu pro nastavovaci AP (default je 3), po nacteni konfiguracni stranky je nastaveny timeout na 6 minut, pokud je ve jmenu SSID pro konfiguracni
- *					  AP znak ? (otaznik), tak je tento nahrazen HEXASCII reprezentaci 3 poslednich bytu MAC adresy AP (POZOR!!! je jina, nez STA!!!)
- *
- * V4.4 - 10.7.2016 - Zmena nazvu vsech privatnich metod (doplnene uvodni podtrzitko _). Pokud tam nebylo, tak napriklad nesel prelozit skript s handleNotFound pokud nebyl dopredne deklarovany (asi zmatek v Arduino preprocesoru)
- *
- * V4.3 - 23.6.2016 - Kazde nacteni webove stranky prodluzuje pripadny timeout pro restart zarizeni.
- *
- * V4.2 - 10.6.2016 - DNSServer a WebServer ukazatele jsou nyni staticke primo v modulu WiFiConfig. Predchozi verze neumoznila soucasne pouziti s knihovnami ESPAsyncWebServer z duvodu kolize nekterych definic HTTP metod
- *
- * V4.1 - 18.5.2016 - Nenechame SDK ukladat WiFi konfiguraci do Flash (setrime prepisy)
- *
- * V4.0 - 10.4.2016 - pridana moznost staticke konfigurace ip parametru. POZOR!!!! ukladani dat do EEPROM (verejne funkce) nyni nevolaji automaticky commit() kvuli snizeni poctu prepisu Flash EEPROM
- * 					  pridana moznost timeoutu pro konfiguracni AP. Pokud timeout vyprsi, tak se zarizeni automaticky restartuje, coz vyvola novy pokus o pripojeni.
- *
- * V3.0 - 27.2.2016 - pridana presmerovavaci stranka kvuli Captive portalu, doplneno servirovani favicon.ico, doplnena moznost zadavani uzivatelskych parametru, www server a DNS server jsou dynamicky vytvareny
- *
- * V2.4 - 7.2.2016  - upraveno casovani pri pripojovani k AP (zmizel delay(100))
- *
- * V2.3 - 5.2.2016  - pridano zverejneni jmena hosta a nastaveni tohoto jmena pro DHCP apod.
- *
- * V2.2 - 19.1.2016 - pridan Captive portal pri konfiguracnim AP.
- *
- * V2.1 - 20.9.2015 - pridano zadavani jmena zarizeni. Modul ho sice nevyuziva, ale aplikace ano a v pripade DHCP se dost hodi.
- *
- * V2.0 - 30.8.2015 - Podstatnym zpusobem vylepsena signalizace vnitrniho stavu, presunuto ulozeni rezimu (commit je uz zbytecny - udela se pri ukladani retezcu - uspora kodu/setreni prepisu pameti Flash)
- *
- * V1.2 - 23.8.2015 - BugFix - pridan chybejici eeprom.commit() po ulozeni rezimu prace
- *
- * V1.1 - 5.8.2015 - pridana moznost volani callback metody pri behu konfiguracniho AP (signalizace stavu uzivatelskym zpusobem)
- *
- * V1.0 - publikace na www.xpablo.cz
- *
- * TODO:
- * Prejit na pripojovani pomoci vnitrnich mechanizmu SDK ESP - zvysi se tim rychlost pripojeni kvuli bateriovym zarizenim

+ *                      verze pro ESP32 zobrazuje neco malo informaci o stavu pripojeni a duvodu vstupu do WifiConfig
+ *
+ * V6.3.1- 1.9.2019 - Odstraneni HTML5 validatoru - delaly akorat problemy a nedala se ulozit konfigurace i kdyz byly polozky skryty
+ *
+ * V6.3 - 12.8.2019 - IP adresa Captive portalu je zmenena na 172.217.28.1 kvuli funkcnosti na Android zarizenich (viz. zmena zde https://github.com/esp8266/Arduino/blob/master/libraries/DNSServer/examples/CaptivePortal/CaptivePortal.ino)
+ *             ladici vypis pri zachyceni presmerovani v Captive portalu.
+ *
+ * V6.2 - 12.12.2018- Nastaveni jmena zarizeni nadale NENI soucasti WiFiConfig a je treba ho pridat jako uzivatelsky parametr. Je to proto, protoze
+ *             se ukazalo, ze neni dobre z externiho kodu sahat do vnitrni struktury WiFiConfig (napr. pri ukladani noveho jmena).
+ *
+ * V6.1 - 11.12.2018- Sifrovani retezcu vytazeno mimo WiFiConfig do knihovny encipheredEEPROMStrings (dostupna na gitu) kvuli pristupu i jinych modulu
+ *
+ * V6.0 - 20.11.2018- Verze i pro ESP32
+ *
+ * V5.9 - 18.7.2018 - Retezce, ukladane do EEPROM jsou primitivnim zpusobem sifrovany pro ztizeni odhaleni SSID a hesla pri dumpu pameti
+ *
+ * V5.8 - 5.7.2018 - Opraveno spatne zobrazovani sily signalu v prehledu WiFi siti (spatne barvy)
+ *
+ * V5.7 - 4.7.2018 - BugFix - staticka konfigurace ip adresy se neuplatnila - vypada to, jako kdyby SDK ukladalo SSID a Password, ale uz neuklada
+ *            konfiguraci ip adres, takze je treba je vzdycky nastavit znovu
+ *
+ * V5.6 - 1.7.2018 - BugFix - odstraneno volani _plusDecode, protoze parametry jsou nyni predavany v 'ciste' forme uz z weboveho serveru a tato metoda znehodnotila retezce, ktere obsahovaly ynak '+'
+ *
+ * V5.5 - 3.6.2018 - Flash Chip ID a ESP Chip ID jsou zobrazeny hexadecimalne v prehledove strance
+ *
+ * V5.4 - 9.1.2018 - na titulni stranku pridan duvod, proc je spusteny konfiguracni AP. Usnadni to diagnostiku pripadu, kdy se ESP nechce pripojit k AP.
+ *
+ * V5.3 - 8.12.2017 - prepracovano presmerovani v Captive portalu, DEBUG_MSG makro upraveno na posledni pouzivanou verzi, scitani retezcu prepracovano na .concat. Pripsany Informace o modulu, reakce na Reset
+ *
+ * V5.2 - 20.4.2017 - Pokud je pouzite v timeoutu WC_DONT_RUN_CONFIGAP tak se vracime okamzite a necekame na pripojeni k WiFi (take nevolame zadnou callback metodu).
+ *            Navratovy kod je pak WCR_CONFIGAP_NOT_STARTED .
+ *
+ * V5.1 - 3.4.2017  - Webove rozhrani upravene pro snadnejsi ovladani na telefonu/tabletu, sila signalu AP zobrazena jako barevne odliseny indikator.
+ *
+ * V5.0 - 29.10.2016- Vyuziti vlastnosti ESP, ktere si uklada wifi konfiguraci do sve vlastni flash oblasti, takze nemusim vse konfigurovat znovu po startu - doufam, ze se tim zrychli asociace s AP
+ *            kvuli bateriove napajenym pristrojum.
+ *
+ * V4.7 - 30.8.2016 - Metody .begin se nyni vraci s wificonfigresult_t (podarilo se pripojit k AP, nepodarilo se pripojit a vyprsel timeout pro konfiguracni AP, nepodarilo se pripojit, ale je zakazane spousteni konfiguracniho AP).
+ *            ESP NYNI NENI RESETOVAN PO VYPRSENI TIMEOUTU!!!! Je to kvuli bateriovym cidlum a DeepSleep rezimu v situaci, kdy zmizi AP, ke kteremu se bezne pripojujeme
+ *            Odstraneno odesilani reakce na generate_204 (viz. https://github.com/tzapu/WiFiManager/issues/114)
+ *            Zbytek MAC adresy v pripadnem SSID je nyni vzdy velkymi pismeny (UAA Unique Address Assignment)
+ *            Kvalita signalu jednotlivych AP je nyni uvadena v % namisto uzivatelum nic nerikajicich -dBm
+ *            Pokud do polozky timeout v .begin() metode zadame hodnotu WC_DONT_RUN_CONFIGAP, tak i po neuspesnem pokusu o pripojeni do site NENI spusteny konfiguracni AP (bateriove pristroje, stale bezici pristroje)
+ *
+ * V4.6 - 26.7.2016 - Moznost nastavit cislo kanalu pro rezim AP, nove eye-candy rozhrani.
+ *
+ * V4.5 - 20.7.2016 - Moznost konfigurovat cislo kanalu pro nastavovaci AP (default je 3), po nacteni konfiguracni stranky je nastaveny timeout na 6 minut, pokud je ve jmenu SSID pro konfiguracni
+ *            AP znak ? (otaznik), tak je tento nahrazen HEXASCII reprezentaci 3 poslednich bytu MAC adresy AP (POZOR!!! je jina, nez STA!!!)
+ *
+ * V4.4 - 10.7.2016 - Zmena nazvu vsech privatnich metod (doplnene uvodni podtrzitko _). Pokud tam nebylo, tak napriklad nesel prelozit skript s handleNotFound pokud nebyl dopredne deklarovany (asi zmatek v Arduino preprocesoru)
+ *
+ * V4.3 - 23.6.2016 - Kazde nacteni webove stranky prodluzuje pripadny timeout pro restart zarizeni.
+ *
+ * V4.2 - 10.6.2016 - DNSServer a WebServer ukazatele jsou nyni staticke primo v modulu WiFiConfig. Predchozi verze neumoznila soucasne pouziti s knihovnami ESPAsyncWebServer z duvodu kolize nekterych definic HTTP metod
+ *
+ * V4.1 - 18.5.2016 - Nenechame SDK ukladat WiFi konfiguraci do Flash (setrime prepisy)
+ *
+ * V4.0 - 10.4.2016 - pridana moznost staticke konfigurace ip parametru. POZOR!!!! ukladani dat do EEPROM (verejne funkce) nyni nevolaji automaticky commit() kvuli snizeni poctu prepisu Flash EEPROM
+ *            pridana moznost timeoutu pro konfiguracni AP. Pokud timeout vyprsi, tak se zarizeni automaticky restartuje, coz vyvola novy pokus o pripojeni.
+ *
+ * V3.0 - 27.2.2016 - pridana presmerovavaci stranka kvuli Captive portalu, doplneno servirovani favicon.ico, doplnena moznost zadavani uzivatelskych parametru, www server a DNS server jsou dynamicky vytvareny
+ *
+ * V2.4 - 7.2.2016  - upraveno casovani pri pripojovani k AP (zmizel delay(100))
+ *
+ * V2.3 - 5.2.2016  - pridano zverejneni jmena hosta a nastaveni tohoto jmena pro DHCP apod.
+ *
+ * V2.2 - 19.1.2016 - pridan Captive portal pri konfiguracnim AP.
+ *
+ * V2.1 - 20.9.2015 - pridano zadavani jmena zarizeni. Modul ho sice nevyuziva, ale aplikace ano a v pripade DHCP se dost hodi.
+ *
+ * V2.0 - 30.8.2015 - Podstatnym zpusobem vylepsena signalizace vnitrniho stavu, presunuto ulozeni rezimu (commit je uz zbytecny - udela se pri ukladani retezcu - uspora kodu/setreni prepisu pameti Flash)
+ *
+ * V1.2 - 23.8.2015 - BugFix - pridan chybejici eeprom.commit() po ulozeni rezimu prace
+ *
+ * V1.1 - 5.8.2015 - pridana moznost volani callback metody pri behu konfiguracniho AP (signalizace stavu uzivatelskym zpusobem)
