Templatized all functions using String or std::string

Browse Source 
* Removed `ArduinoJson::String`
* Removed `JsonVariant::defaultValue<T>()`
* Removed non-template `JsonObject::get()` and `JsonArray.get()`
* Fixed support for `StringSumHelper` (issue #184)
* Replaced `ARDUINOJSON_USE_ARDUINO_STRING` by `ARDUINOJSON_ENABLE_STD_STRING` and `ARDUINOJSON_ENABLE_ARDUINO_STRING` (issue #378)
* Added example `StringExample.ino` to show where `String` can be used

* Templatized all functions using `String` or `std::string`
* Removed `ArduinoJson::String`
* Removed `JsonVariant::defaultValue<T>()`
* Removed non-template `JsonObject::get()` and `JsonArray.get()`
* Fixed support for `StringSumHelper` (issue #184)
* Replaced `ARDUINOJSON_USE_ARDUINO_STRING` by `ARDUINOJSON_ENABLE_STD_STRING` and `ARDUINOJSON_ENABLE_ARDUINO_STRING` (issue #378)
* Added example `StringExample.ino` to show where `String` can be used
* Increased default nesting limit to 50 when compiled for a computer (issue #349)
**BREAKING CHANGES**:
The non-template functions `JsonObject::get()` and `JsonArray.get()` have been removed. This means that you need to explicitely tell the type you expect in return.
Old code:
```c++
#define ARDUINOJSON_USE_ARDUINO_STRING 0
JsonVariant value1 = myObject.get("myKey");
JsonVariant value2 = myArray.get(0);
```
New code:
```c++
#define ARDUINOJSON_ENABLE_ARDUINO_STRING 0
#define ARDUINOJSON_ENABLE_STD_STRING 1
JsonVariant value1 = myObject.get<JsonVariant>("myKey");
JsonVariant value2 = myArray.get<JsonVariant>(0);
```
v5.6.7
