Added the get_object() method.

2000-02-03  Federico Mena Quintero  <federico@helixcode.com>

	* evolution-calendar.idl (Cal): Added the get_object() method.

	* cal-client.c (cal_client_get_object): New function to get a
	calendar object by its UID.

	* cal.c (Cal_get_object): Implemented.

	* cal-backend.c (cal_backend_get_object): New unfinished backend
	function.  We need some reorganizing of how the calendar objects
	are stored.
