Micropython support for control/webserver.py

[dwalton76]

I have experimented with https://github.com/jczic/MicroWebSrv and it seems to work fairly well. I haven't tested to see how will that library works with python3 though. It might be a decent starting point though if we decide we want to support WebControlledTank in micropython. It takes forever (I want to say more than 30s) to load WebControlledTank via python3.

I think this could be cool, but from a time investment perspective the reward probably isn't worth it for now. My thought is that uPy is, in general, designed to be small -- do just the simple things, but really fast. If someone wants a whole web server running there's probably enough work to be done there that they're willing to/will want to use full CPython instead. That doesn't prevent us from supporting it if it turns out someone has the time and wants to go for it though.
