automation: implement "publish-windows-artifacts" command
The new command and associated functionality can be used to
automate the publishing of Windows release artifacts. It
supports uploading wheels to PyPI (using twine) and copying
the artifacts to mercurial-scm.org and updating the latest.dat
file to advertise them via the website.
I ran `automation.py publish-windows-artifacts 5.1.1` and it
appeared to "just work." But the real test will be to do this
on the next release...
