Bugfixing and adding missing libraries, login framework  works now within
Coacheller-AppEngine
Fixed: FestivalEnum.equals(FestivalEnum otherEnum) now checks if the other
enum is null...

Fixed: Nasty bug where a duplicate AuthProviderAccount entry could be
created when the user accomplishes the same login multiple times, or logs
out and back in to RTF.  Bug survived for a long time because generally
the UI does not allow you to log in to i.e. twitter multiple times over.

Created widget for title banner image, shows correct image based on host
name

Login widget in progress, facebook logins have an issue due to the use of
different domain names
