    editor: rework the response handling of the advanced dialog
    
    This utilizes the actions and the response callback to deal with the
    dialog response and differentate between a positive and a negative
    response.
    
    It also switches to using the HeaderBar, because that's looks better and
    works better with Gtk4.
