	* pcs/cal-backend-file.c (cal_backend_file_class_init): override
	virtual function
	(cal_backend_file_is_remote): new virtual function, always return
	FALSE

	sequence
	(cal_client_uri_list): factory call to get uri list

	* cal-client/cal-client.h: new proto

	* cal-client/cal-client.c: use bonobo exception stuff to clean
	code

	* gui/calendar-offline-handler.[hc]: Start some skeleton routines
	for online/offline handling
