    network: Make connection editor dialog use a headerbar
    
    In order to start moving towards the new redesigned connection
    editor [1], it is necessary to make the dialog use a headerbar.
    
    Currently, however, it doesn't, making the connection editor
    dialog inconsistent with the rest of the panels, and the GNOME
    desktop as a whole.
    
    Fix that by exporting the buttons as action buttons, and setting
    the use-header-bar property to TRUE.
