[cheese] Use a traditional title bar when requested

[David King <davidk src gnome org>]

commit f0edb1f9794cebe0f5be8052824e7e07d023efc8
Author: Iain Lane <iain lane canonical com>

    Use a traditional title bar when requested
    
    Not all environments desire header bars. We use the
    'gtk-shell-shows-menubar' setting to decide whether to use the header
    bar.
