localhost option for x0vncserver

[Hein Roehrig]

Dear *,

the following simple patch (against the Debian vnc4 package) makes
x0vncserver behave more like vncserver in that it accepts the
-localhost option to bind the VNC port to localhost. This is nice to
have when tunneling a x0vncserver session over SSH.

Thanks,
Hein
