* gladeui/glade-app.[ch]: Removed glade_app_widget_event() and the "widget-event"
	  signal

	* gladeui/glade-design-layout.c: Expose glade_design_layout_widget_event() to
	  be used internally by GladeWidget (no longer listening to "widget-event" signal
	  on glade-app).

	* gladeui/glade-widget.c: glade_widget_event_private() Find the parenting
	  GladeDesignLayout and dispatch the event through glade_design_layout_widget_event()
	  (this fixes multiple projects recieving the same events, bug 456013).
