Use menu_shell->children, not menu->children. Why does GtkMenu have a

1998-04-16  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* eventedit.c (ee_store_alarm): Use menu_shell->children, not
	menu->children.  Why does GtkMenu have a children field in the
	object structure?
	(check_dates): New function that insures that start_date < end_date.
	(check_times): In addition to checking whether the event spans the
	whole day, now it insures that start_time < end_time.

	* gncal-full-day.c (child_set_size): Now children get bigger
	temporarily while they are focused.  This allows the handles not
	to "overlap" the rows used by the child and thus allow editing of
	very thin events.
	(recompute_motion): Fix for new child coordinates.
	(gncal_full_day_expose): Make it use find_child_by_window()
	instead of looking for it by hand.
