	* gui/dialogs/alarm-dialog.c (palarm_widgets_to_alarm): the args
	are optional, don't store them if they aren't there
	(check_custom_sound): sensitize the ok button based on whether or
	not there needs to be input
	(check_custom_message): ditto
	(check_custom_program): ditto
	(dalarm_message_toggled_cb): check custom message
	(dalarm_description_changed_cb): ditto
	(aalarm_sound_toggled_cb): check custom sound
	(aalarm_attach_changed_cb): ditto
	(palarm_program_changed_cb): check custom program
	(action_selection_done_cb): use above checks as appropriate
	(init_widgets): listen for changed signals
