committing recent renderer changes to this branch. weird bug where collisions occur regardless of json
Collisions now being triggered, breakout now working but pong broken.
- Changed the joint to be ZSComponentNode because it was being cast as such in the didBeginContact method.
- Added a physics body to fix a bug that caused the app to crash when a node was touched.
Modified pong json to increment a score each time the ball hits the paddle.
- There is a bug that causes the score to go up twice when a paddle is being dragged.
- There is a bug where it appears that the joint consumes the ball, even when it’s not on the edge of the screen.
Refactored ZSRendererScene, still has crashing bug with touch events.
Whitespace and comment fixes.
