Chain to the destroy handler in the parent class!

2001-08-09  Federico Mena Quintero  <federico@ximian.com>

	* gui/e-itip-control.c (destroy): Chain to the destroy handler in
	the parent class!

	* gui/dialogs/comp-editor-page.c (comp_editor_page_destroy):
	Likewise.  Sigh.

	* gui/cal-search-bar.c (cal_search_bar_destroy): Whoops, added a
	destroy handler.
