Modernized and simplified the app.

This wasn't a crazy rewrite or anything, I just updated it to the new
YouTube Transcript and OpenAI API's, as well as super simplifying the
code. On top of that, it now works single threaded, just using multiple
gunicorn threads for concurrency. It's a lot simplier and cleaner,
although not up to my current standards.
