Using websockets because it would be nice to eventually have a terminal
in the Electron client.
This is prototype-quality code. Using the built-in client/server from the
`websockets` package, but that's just for testing.
Joe told me to look at the Jaque terminal and I just did. That uses
the Lanterna Java library to handle terminal output. Joe then suggested
that I move the entire system here to curses or another similar library.
