Stop the timer on destroy, or when we are notified that we are shadowed by

Tue Jan 15 18:10:24 2002  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkspinbutton.c (gtk_spin_button_grab_notify): Stop
	the timer on destroy, or when we are notified that we are
	shadowed by a modal dialog.

	* gtk/gtkspinbutton.c: Remove explicit gtk_grab_add()/remove() -
	not needed any more.

	* gtk/gtkmain.c (gtk_grab_notify): Fix problem where notifications
	weren't sent out for the default grab group.

	* gtk/gtkmain.c (gtk_grab_notify): Fix notification of widgets that
	were getting events because they were part of the previous grab.
