Support for repeat/duration properties in alarm components.

2001-07-02  Federico Mena Quintero  <federico@ximian.com>

	Support for repeat/duration properties in alarm components.

	* cal-util/cal-component.h (CalAlarmRepeat): New structure that
	pairs the repeat/duration values of an alarm component, which must
	be set both together or not set at all.

	* cal-util/cal-component.c (CalComponentAlarm): Added fields for
	the repeat and duration properties.
	(scan_alarm_property): Scan the DURATION and REPEAT properties.
	(make_alarm): Nullify/initialize all the fields in the alarm.
	(cal_component_alarm_get_repeat): New function.
	(cal_component_alarm_set_repeat): New function.

	* gui/dialogs/alarm-page.glade: Changed the label of display
	alarms from "Show a dialog" to "Display a message".
