use a cache to keep the objects from the server.

2003-12-03  Rodrigo Moya <rodrigo@ximian.com>

	* backends/groupwise/e-cal-backend-groupwise.c: use a cache
	to keep the objects from the server.
	(e_cal_backend_groupwise_finalize): unref the cache object.
	(e_cal_backend_groupwise_open): load/create the local cache.
	(e_cal_backend_groupwise_get_object): look for the object in
	the cache.
	(e_cal_backend_groupwise_class_init): fixed warning.
