end drag selections if necessary.

Mon Jan 11 23:52:58 1999  Lars Hamann  <lars@gtk.org>

	* gtk/gtklist.c (gtk_list_signal_drag_begin)
	(gtk_list_drag_begin): end drag selections if necessary.

	* gtk/gtkspinbutton.c/h (gtk_spin_button_update): made function
	public. Manually force synchronization of spin button text and
 	adjustment value.
