First cut at a ZServer NT service. This is Zope on NT's answer to zdeamon.py

It actually seems to work, though there's still a fair amount missing.

ZServer as a NT service.
The serice starts up and monitors a ZServer process.
Features:
* When you start the service it starts ZServer
* When you stop the serivice it stops ZServer
* It monitors ZServer and restarts it if it exits abnormally
* If ZServer is shutdown from the web, the service stops.
* If ZServer cannot be restarted, the service stops.
TODO:
* Document it.
* Integrate it into the Windows installer.
* Figure out a solution for ZServer information, i.e. remembering/
setting commandline args, knowing where Python is, etc.
* Add event logging.
* Get Zope version from Zope
This script does for NT the same sort of thing zdeamon.py does for UNIX.
Requires Python win32api extensions.
