Added the new way to process invites for club_admin only. This patch contains the separability needed to ensure that we can successfully do the access checks we need. Host invites can for the time being only be completed by developers due to the reorganization. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed

 This module houses the GEOS exceptions, specifically, GEOSException and

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
