Fixes pip

I had previously set up the `pip` configuration incorrectly (none of the paths were pointing to the write thing, and some packages were not being included). This PR fixes that.

This PR also adds the `ok-publish` command line tool, so that staff users of `ok.py` can publish a zip archive from anywhere within their project repo.
Haha, it's fine. I was just curious. I don't think we're running out of numbers soon. :P
