Update to tightvncviewer-1.3.9.
Major upstream changes to the viewer are:
1.3.9
-----
 o Added support for the standard RFB protocol version 3.8 with TightVNC
   extensions.

1.3.8
-----
 o Port numbers are now calculated modulo 65536 with vncviewer's -listen
   option. That makes it possible to listen on TCP ports under 5900.

1.3dev4
-------
 o Fixed a bug with the viewer crashing on selecting text in Xvnc,
   and then choosing F8 / Clipboard: local -> remote, twice.
