add overrides for Xtightvnc invocation #7

So I've just gotten this working on a CentOS system. For reasons beyond my understanding, Debian derivatives ship with TightVNC, but RedHat derivatives use TigerVNC. This results in different executable naming (/usr/bin/Xvnc vs /usr/bin/Xtightvnc) and different defaults. In particular, TigerVNC defaults to security settings that wind up requiring the user to input a (not existing) password.

In my CentOS container I got around this by creating a /usr/bin/Xtightvnc shell script like:

#!/bin/sh
exec /usr/bin/Xvnc $@ -localhost -SecurityTypes=None

But it would be nicer to be able to either configure the command that supervisor runs, or at least drop a script like that in a less-hardcoded location.

Does 5a64d9e suffice? You could set it to be your wrapper script or to the expanded command that is run from it.

That definitely ought to do the trick. I'll let you know once I've had a chance to test it, but I expect that'll work.
