TODO Add Chess

[TISHARP]

Problem:

Currently there is no Chess game added to our two player offerings.

Proposal:

We need to implement a minimal solution to chess and add it to our project. In the event that such addition is large we can lazy load the code for it and suspend it until we actually launch the game.
