Add instructions for deploying in production

[rjurney]

I want to deploy this in production so that task workers (in this case friends) can help me label data. It would be great if someone did this and documented it. Since nobody has, I suppose that will be me.

But by all means, if anyone has done this - please let me know!

I happened to do this a couple of weeks ago. The whole process was actually very simple: I updated the prod Dockerfiles so that an image could be built. However, it does seem like that I've been running the development server (that is python ./manage.py runserver 0.0.0.0:8000) the whole time so I guess it would need a bit more work.

If you'd be up for putting this documentation together, please let me know -- I'd be happy to help!

The prod images do not build. Lots of things seem to be broken (paths and python versions). The dev images work fine though.
