* Better usage of cache for group retrieval * Cache clearing on object deletion or update * replace signals by save and delete override * add is_anonymous check in is_owned_by Add in many is_owned_by(self, user) methods that user is not anonymous. Since many of those functions do db queries, this should reduce a little bit the load of the db. * Stricter usage of User.is_in_group Constrain the parameters that can be passed to the function to make sure only a str or an int can be used. Also force to explicitly specify if the group id or the group name is used. * write test and correct bugs * remove forgotten populate commands * Correct test
