Added a User_username table that links the external username with a StatusNet user_id 

Added EmailAuthenticationPlugin
Added ReverseUsernameAuthenticationPlugin
Changed the StartChangePassword and EndChangePassword events to take a user, instead of a nickname
User::allowed_nickname was declared non-static, but used as if it was static, so I made the declaration static
