- Fix #443005 by using the pid from the pidfile rather than that of runzope.exe

- correct capitalisation of "command" reg value name, not that it matters ;-)
- add a windebug command to help when debugging windows service behaviour
- refactor do_start: nt_svcutils.service.Service sets ZMANAGED, so its not needed on Windows.
