[nautilus/wip/coreyberla/app-picker-followups: 1/5] app-chooser: Replace Reset and Set as Default buttons with a Switch

[Corey Berla <coreyberla src gnome org>]

commit 6ff6efc6fcc96916712039d03234b80895a8a8c5
Author: Corey Berla <corey berla me>

    app-chooser: Replace Reset and Set as Default buttons with a Switch
    
    Set the switch to active when the association is set as default
    and inactive when it is not set as default (also a way to remove
    the default association).  Add a label for the switch with a
    subtitle indicating the content description.
