Update net/tightvncviewer to 1.2.8.  Changes from version 1.2.7 include:

    * Support for a separate view-only password has been implemented. Now
      the servers support two passwords -- one to allow full control,
      another to restrict remote keyboard and mouse input.

    * New "-x11cursor" option has been implemented in vncviewer. This \ 
option
      allows using a real X11 cursor with X11-style cursor shape updates,
      disables the dot cursor, and disables cursor position updates in
      non-fullscreen mode.

    * New "RunCommand" command to customize the X11 vncviewer popup \ 
menu has
      been implemented; a patch from Peter Astrand.

    * A problem with Xvnc eating all CPU time after xfs restarts has been
      fixed.

    * Other minor improvements and bugfixes.
