Added an use_description argument so that other alarms can fall back to

2001-09-11  Federico Mena Quintero  <federico@ximian.com>

	* gui/alarm-notify/alarm-queue.c (display_notification): Added an
	use_description argument so that other alarms can fall back to
	this type.
	(audio_notification): Implemented.
	(remove_comp): Call remove_queued_alarm() here; there is no longer
	a destroy notification function for alarms so must we do this
	manually.
	(alarm_trigger_cb): Do not pass the alarm to the notification
	functions so that we can free it ourselves before all the alarms
	in the component get freed.
	(display_notification): Get the alarm here instead of getting it
	as an argument.
	(procedure_notification): Implemented.
