    window: Differentiate debug instances from normal ones
    
    When running a debug instance alongside the regular Polari instance,
    it is easy to lose track of which is the temporary one. Address this
    by adding some subtle styling hints in the debug instance's title bar.
    
    Fixes https://gitlab.gnome.org/GNOME/polari/issues/24
