	Switch the alarm system from using SIGALRM to normal glib timers.
	Also, use a more robust de-queueing mechanism.

	* gui/alarm-notify/alarm.c (alarm_init): Removed.
	(alarm_done): Remove the glib timeout instead of closing the pipes
	and the signal handler.
	(alarm_add): Allow adding alarms that happen before right now.
	(queue_alarm): Use a glib timer instead of a signal.
	(alarm_remove): Adjust the timeout as appropriate.

	* gui/alarm-notify/notify-main.c (main): There is no need to
	initialize the alarm system now.

	* gui/main.c (main): Likewise.
