Auto-killing the VNC server

open source is a beautiful thing.  add this at the end of the rfbCloseSock
function in vnc_unixsrc/Xvnc/programs/Xserver/hw/vnc/sockets.c:
dispatchException |= 2;  /* DE_TERMINATE */

also add at the top:
extern char dispatchException;

this effectively kills and cleans up the server when a client connection
is lost.

happy hacking.
