Title: Chingu refactoring

Had a bit of change of heart on how I was handling x & y.

- Broke the draw logic out into a GridSprite trait that handles the offset itself.
- Broke the grid positioning logic out into GridPosition trait.

This way x & y are back to being the grid co-ordinates and we have reusable traits for any new objects that need to go into the grid.
