if we already have the client loaded, don't remove it, just increment its

2003-03-09  Rodrigo Moya <rodrigo@ximian.com>

	* gui/alarm-notify/alarm-notify.c (alarm_notify_add_calendar): if we
	already have the client loaded, don't remove it, just increment its
	reference count.

	* gui/alarm-notify/alarm-queue.c (remove_queued_alarm): added new
	argument to specify whether we want the component's structure removed
	if no more alarms exist, and only free the structure if TRUE.
	(remove_alarms): added same new argument and pass it over to
	remove_queued_alarm.
	(remove_comp, obj_updated_cb): passed new argument to remove_alarms.
	(procedure_notification): passed new argument to remove_queued_alarm.
	(obj_removed_cb): set all freed pointers to NULL.
	(notify_dialog_cb): only remove the alarm if the pointers are not NULL.
