New function to create the base VObject for a calendar.

2000-02-04  Federico Mena Quintero  <federico@helixcode.com>

	* cal-backend.c (get_calendar_base_vobject): New function to
	create the base VObject for a calendar.
	(cal_backend_get_object): Create the base calendar and add the
	sought object to it, then stringify it.

	* evolution-calendar.idl (Listener::obj_added
	Listener::obj_changed): Now these pass in just the UIDs, not the
	complete objects.

	* cal-listener.c (Listener_obj_added): Changed to pass in the uid,
	not the object.
	(Listener_obj_changed): Likewise.

	* cal-client.h (CalClientClass): Made the obj_added and
	obj_changed signals take in the UIDs, not the full objects.

	* cal-client.c (obj_added_cb): Likewise.
	(obj_changed_cb): Likewise.
