    GtkHeaderBar: Fixed property sensitivity issues
    
    The custom editor was calling glade_widget_property_set_sensitive()
    directly which does not work with undo/redo.
    
    Cleaned up the editor and adaptor so that the editor issues commands
    and the adaptor->set_property() adjusts property sensitivity when
    'show-close-button' and 'use-custom-title' properties change.
    
    Also some minor changes to the gtk+.xml.in, no need for the
    decoration layout property to be optional really, since the property
    is a string and will not be saved if it's not set.
