	deleting a calendar component.

	* gui/e-day-view.c (e_day_view_on_delete_appointment): Confirm
	before actually deleting the appointment.

	* gui/e-week-view.c (e_week_view_on_delete_appointment): Likewise.

	* gui/dialogs/Makefile.am (libcal_dialogs_a_SOURCES): Added
	delete-comp.[ch] to the list of sources.

	* cal-util/cal-component.c (cal_component_destroy): Free the alarm
	UID hash.
