Swap out Flask's default web server for Waitress (#32)

* Ignore venv when building docker file

* Remove reference to 8888 port

It wasn't really used anywhere, and setting it to 5000 everywhere removes ambiguity, and makes things easier to track and reason about

* Use waitress rather than Flask's built in web server

It's not production grade

* Actually add waitress to requirements

Woops!
