* plugins/gtk+/gtk+.xml.in: Faked the accel-group property and added
	accel-groups object list to GtkWindow... work in progress.

	* plugins/gtk+/glade-image-item-editor.c: Adjusted for accel-group property
	which is only avaiable for stock items.

	* plugins/gtk+/glade-gtk.c: Fixed sensitivity for accel-group/stock at load time.

	* gladeui/glade-editor-property.c: Labels dont go insensitive anymore, I think that
	was a general usability problem, the inputs still go insensitive and there are always 
	useful tooltips, the insensitivity message still gets across.

	* gladeui/glade-editor-table.c: Fixed breaking weak refs from dispose.
