[Twisted-Python] win32 buildbot

[Itamar Shtull-Trauring]

Thanks to the efforts of Cory and Norfolk, we now have a working win32
buildbot. So, it's time to get all tests passing. Everyone please take a
moment to look at what's failing and see if it's code you're responsible
for. Fixes to win32event reactor or a finished IOCP reactor so we can
abandon it are welcome ;)
