Kiwi Updates.

- Sprite/StaticImage GameObject's now check to see if the TextureAtlas passed is 'undefined' or not before executing code.
   - If found not to be valid, the game no longer breaks and a nicer error message get's logged out.
- CameraManagers render method is no longer executed if the current state is not found. This prevents forcing the developer to pass a state.
- Tilemap paralax example now goe's vertically. Also spritesheet includes transparency.
