[balsa/gtk4: 62/193] Various: Fill some menus with stateless GMenuItems




commit d09a1a76938e10c0aefa323108a339df519668dc
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Fri Jun 26 16:21:52 2020 -0400

    Various: Fill some menus with stateless GMenuItems
    
    Fill the open-with menus with stateless GMenuItems, so that they are
    rendered without radio buttons.
    
    Instead of passing the app's name as the state of a stateful GMenuItem,
    pass the GAppInfo itself as GObject data on a convenient object.
