Refactor of all formutil calls
Added possibility to redirect the user to the registration screen if the given login information isn't valid. The ZikulaUsersModule does NOT use this feature, but the ZikulaOpenIDModule will use it to redirect any users trying to login for example via Google not having an account registered yet to the registration screen, refs #901.
