Moved the calendar backend here. This is the actual calendar-handling

2000-01-18  Federico Mena Quintero  <federico@helixcode.com>

	* cal-backend.c cal-backend.h: Moved the calendar backend here.
	This is the actual calendar-handling object.
	(load_from_vobject): Moved over from calendar.c.  Modified to use
	a CalBackend instead of the old Calendar structure.
	(add_object): Likewise.

	* cal.c: Now the Cal object is just a calendar client interface
	object; we use it as a "viewport" onto a CalBackend.  This also
	lets us do correct resource management.

	* cal-common.h: New file with common forward declarations; we
	can't have circular dependencies between headers.

2000-01-18  Federico Mena Quintero  <federico@helixcode.com>

	* cal-factory.c (cal_factory_load): Queue a load job.
	(load_fn): Load job handler.  Lookup the calendar by URI, load it
	if it is not loaded, or just report it to the new listener if it is.

	* job.c job.h: New files with a simple job queue manager.

	* gnome-calendar.idl (Listener::cal_loaded): Do not return the
	whole calendar object string.  The client will be able to query
	the calendar for the events it needs.

	* cal-listener.c (Listener_cal_loaded): Ref the calendar GNOME
	object.  We unref it when the listener is destroyed.

	The files from the gncal directory of the gnome-pim module on CVS
	were moved here, to evolution/calendar, in preparation for the
	Evolution work.  The calendar is being split into a model/view
	architecture.  The model is a personal calendar server (PAS):  it
	provides storage, notification, and event generation; the
	views/controllers are the calendar user agents and things like
	Pilot synchronizers.
