You can now delete games via the Matrix bot

Also, I made the delete endpoint return JSON.

v0.1 Initial Version

The program now matches what I had in Flask and even adds a bit in the form of the /delete_game endpoint. I think there may be a bug or two, but I'll have to see over the next few days as I dogfood it. Haven't yet developed the unit tests, but I've got those on the docket for v0.2. So if I don't solve it before then, hopefully I'll catch it with some unit tests.
