    icon: Pick the right icon based on application_id
    
    With the introduction of Nightly icons, we can make it much easier
    for users to differentiate visually an unstable instance of Boxes
    from its stable counterpart.
    
    By having two icons named consistently with our application_ids
    (org.gnome.Boxes.svg for stable and org.gnome.BoxesDevel for unstable),
    we just need to set the icon path to be variabled based on the
    application_id.
    
    Fixes #408
