Feature: TUI/CLI for debugging chess-ray/chess-server

[dmgolembiowski]

As a user, I want to play chess from the command line by entering my movements with the keyboard, and submitting them with Enter. I want to see the gradual progression of the game with some visual feedback on the console.

As a developer, I want to support dumping/loading game state so that I have a way to test scenario-based logic.

It's more practical at this time to create a simple REPL that can be used for debugging chess-ray. Ideally, we want to have it receive debugging information over the network to intercept debugging information, as well as being able to query when RayTiles are not behaving.
