* gladeui/glade-design-layout.[ch]: 
	  Now works like a pure widget, uses gtk_widget_size_allocate() to resize 
	  children and gtk_widget_queue_resize() to resize itself (removed default
	  size control for now).

	* gladeui/glade-xml-utils.[ch], gladeui/glade-widget.[ch], 
	  gladeui/glade-widget-adaptor.[ch], plugins/gtk/gtk+.xml.in,
	  plugins/gtk/glade-gtk.c, plugins/gnome/glade-gnome.c: 
	  - Added glade_xml_get_property_int()
	  - Added default-width/height to catalog/GWA
	  - Added toplevel-width/height properties to GladeWidget
	  - Use default-width/height in catalogs instead of gtk_window_set_default_size()
	    in plugin code.
