Datomic support

First testable beta

No database - everything stored in memory but the engine should work. Walls drawing should work correctly.
Currently has some missing UI elements:

• not clear which color you're in (switching colors of the text)
• no clear way of knowing how to invite a 2nd player when you first play the game
• no rules book or other meta data
