Bug#690365: vnc4server: Add option -autokill

[Stefan Nobis]

Package: vnc4server
Version: 4.1.1+X4.3.0-37
Severity: wishlist
Tags: patch

Dear Maintainer,

it would be nice, if vnc4server has an option '-autokill' to
stop the vncserver as soon as the VNC session run by xstartup
ends.

Appended is a patch for the suggested feature (based on the vncserver
script from tigervnc).
