Adds Python support for data scraping and supplies a permanent database to hold our information.

I really don't know if I'm doing this right, Matt. I everything in the avatar folder (since we can just have Facebook be our CDN), and everything in the setup folder (since it's superseded by the `install/` folder, whose scripts are in Python). I hope the README is self-explanatory, but if not, fire me a FB message.
