Fixes for test suite in win32 when all dependencies (esp. Twisted) are installed. Also activated testing.tools to be picked up by the test suite (was excluded), this gives us a few more tests. Status: - On Linux, the full suite passes like before. - On Win32, now that we have Twisted, we're seeing a few failures, because I don't have the WinHPC server stuff. These should be easy for Brian to fix. There are also two tests where the Skip nose exception isn't recognized by Twisted, should also be easy. I'll file tickets for those.
