git mv context.py -> copycat.py; and start work on a "reporter" API.

The goal here is to use `curses` to display the coderack, slipnet,
and temperature in real time. A further goal would be a reporter
that sent the data over websockets to a browser, at which point
I could throw this thing up on Heroku and let people mess with it.
(Not that that would be very entertaining, yet.)
