Tile update!
- Rehashed entire Tile system to use the same philosophy as Sprites
- Removed Datum and NormalTile
- Updated EngineModule2D to latest version
- Fixed bugs with SpriteRegistry
- Moved a great many static variables to MiTeamMeta, like how they
should've been!
- Fixed that Engine bug which I won't name
- Still need to implement animating for the TileAnimated class, but that
will happen after Christmas
