It is now possible to list the groups that are owned by a user by
GET on '/groups/?owned&user=<user>'. If the 'user' parameter is
omitted the owned groups of the calling user are listed.
Groups can be added by the 'q' parameter to limit the result to
those groups that are of interest to the caller, e.g. if a user wants
to check if he owns group 'MyGroup' he can send this request:
GET /groups/?owned&q=MyGroup
If the group is returned the user owns 'MyGroup'.
