Subject: Adds session management for the alarm daemon. Also makes it store a
 list

2001-10-18  Federico Mena Quintero  <federico@ximian.com>

	Adds session management for the alarm daemon.  Also makes it store
	a list of calendars to be monitored.  Those calendars will all be
	loaded when the alarm daemon starts up.

	* idl/evolution-calendar.idl (AlarmNotify): Removed the ::die()
	method.  The alarm daemon now handles termination via the session
	manager's commands.

	* gui/alarm-notify/notify-main.c (set_session_parameters): New
	function, sets some parameters so that the session manager can
	restart the daemon via the evolution-alarm-client program.  Also,
	sets up the "die" signal so that the daemon can terminate when the
	session ends.
	(load_calendars): New function to load the calendars on startup.
	(main): Set the session parameters.  Load the calendars on startup.

	* gui/alarm-notify/alarm-notify.c (alarm_notify_add_calendar): New
	function, moved over from the impl_ function.  Added a
	load_afterwards argument to indicate whether the calendar should
	just be loaded or if it should also be added to the list of
	calendars to load on startup.
	(AlarmNotify_addCalendar): Use alarm_notify_add_calendar().
	(AlarmNotify_removeCalendar): Remove the calendar from the list of
	calendars to load on startup.

	* gui/alarm-notify/save.c (save_calendars_to_load): New function,
	saves a sequence of the URIs to load.
	(get_calendars_to_load): New function, loads a sequence of
	calendars to load.

	* gui/alarm-notify/alarm.h: Removed stale prototype for alarm_init().

	* gui/component-factory.c (remove_folder): Ask the alarm daemon to
	stop monitoring alarms for the folder that is being deleted.
