Episode 16: Background tiles
Refactoring to screen agnostic. Moved assets to gitignored folder to because I'm adding all the assetsa nd don't want to bloat the repo
Changed to 16x16 graphics
Added config module to help prevent circular dependency complications that we don't have in C++)
Episode 18: Introducing units - created Units module and made functions for enforcing conversions between units.

Underwent masive refactor pulling out manual pixel conversions and removing reliance on Game.kTileSize.
