This repo now only contains the web app.
I did this because they are 2 separate concerns and I have diverged so far from the original repo. I didn't start a new repo because it contains valuable history of all the people who contributed to it. Additionally if there is an issue with this we can revert, but I rather not. Forks are forks.
