[Philip Withnall <pwithnall src gnome org>]

commit a97e74bc3e044fe6d8a55f55f9f8050afcd3ee6d
Author: Philip Withnall <pwithnall endlessos org>

    gs-app: Add a GsApp:permissions property
    
    This exposes the existing permissions functionality, but adds support
    for change notification, which parts of the UI could attach signals to.
