	* gtk/gtkwidget.h (struct _GtkWidgetClass): Added a "grab_focus"
	signal for widgets.  When the signal is emitted, the widget will
	grab the focus.  This is needed to let the user press an
	accelerator key in a dialog box and have the corresponding widget
	be focused.

	* gtk/gtkwidget.c (gtk_widget_class_init): Create the "grab_focus"
	signal.  The default handler is simply gtk_widget_grab_focus().
