[nautilus] Let forward/back mouse buttons work

commit 9826f177cb72fc9f595356b773f51059bef6cd1e
Author: Andrew Walton <awalton gnome org>
Date:   Wed Apr 22 10:57:05 2009 +0200

    Let forward/back mouse buttons work
    
    Install a handler to link forward/back mouse buttons to
    forward/back actions in NautilusNavigationWindow, with a preference
    to set the right X button number in GConf.
