    telepathyClient: Use normal notifications on non-GNOME desktops
    
    Notifications are currently only used for highlights in chat rooms,
    as we assume that GNOME's builtin chat integration will handle private
    conversation notifications. This is not available on other desktops, so
    we should notify in that case as well.
