New method (GtkBuilderConverter._create_object): Conditionally take a node

2008-01-18  Johan Dahlin  <johan@gnome.org>

	* gtk/gtk-builder-convert (get_property_node): New method
	(GtkBuilderConverter._create_object): Conditionally take a node as
	a property value, so don't lose translate/context attributes if they
	are set. 
	(GtkBuilderConverter._add_action_from_menuitem): Send in Node as
	property values instead of strings.
	(#509153, Erik van Pienbroek)
