add signals and binding set, so keybindings are configurable

2001-04-18  Havoc Pennington  <hp@redhat.com>

	* gtk/gtkwindow.c (gtk_window_class_init): add signals and binding
	set, so keybindings are configurable
	(gtk_window_activate_default): Change to activate the focus widget
	instead if there's a focus widget, to be consistent with the
	behavior that previously existed in key_press_event
