of overflowing the id numbers when continusly creating and destroying actors on long running applications for 16bpp. * clutter/clutter-private.h: replaced hashtable with GArray and a GSList for available slots in the array. * clutter/clutter-actor.c: (create_actor_id): function to create an actor->id mapping, (release_actor_id): function to mark an existing id as available for reuse. * clutter/clutter-main.c: (clutter_context_free): added utility function for cleaning up the context, (clutter_get_actor_by_gid): use the GArray for looking up actors.
