* gladeui/glade-widget-adaptor.[ch]: Added glade_widget_adaptor_from_pspec()
	  and made glade_widget_adaptor_from_pclass() always return the owning
	  adaptor and not the adaptor for the class which the property was originally
	  created for.

	* gladeui/glade-editor.[ch]: Removed some deadcode

	* gladeui/glade-editor-property.c: Use glade_widget_adaptor_from_pspec()
	  where appropriate (Fixing bug 423425)
