The Wombat now keeps track of which categories are present in the objects

2001-07-31  Federico Mena Quintero  <federico@ximian.com>

	The Wombat now keeps track of which categories are present in the
	objects of a calendar.  It will notify the clients of changes in
	this set.  This is to make the category drop-down menus in the
	calendar/tasks views be always up to date.

	* idl/evolution-calendar.idl (Listener): Added a
	notifyCategoriesChanged() method.  The Wombat now keeps track of
	the categories within a calendar.

	* cal-client/cal-listener.[ch]: Switched it to use BonoboXObject.
	Also added the notifyCategoriesChanged implementation.

	* cal-client/cal-client.[ch]: Added a "categories_changed" signal.

	* pcs/cal-backend-file.c: Maintain a list of the live categories.
	(update_categories_from_comp): New function to maintain the set of
	live categories.
	(add_component): Update the set of categories.
	(remove_component): Likewise.
	(open_cal): Notify about changes in the set of categories.
	(create_cal): Likewise.
	(cal_backend_file_update_objects): Likewise.
	(cal_backend_file_remove_object): Likewise.
	(notify_categories_changed): New function to notify the clients
	about the current set of categories.

	* pcs/cal.c (cal_notify_categories_changed): New function.
