Subject: [PATCH] Fixed release script issue with fetching recent tags

Fetching all tags was triggering the pagination system inside the github
API. This prevent version tags from being found.

Modified to use the version tag prefix in the ref lookup, however this
still may cause an issue if there are still enough patch releases to trigger
pagination.

Simpleish solution is to grab the link header to jump to the last page,
since pagination results appear to be in sorted order.
