Add particle emitters for brick destruction

- Fades in level indicator;
- Flashes ball when level increases
- Adds a particle element for brick destruction, as well as the code to make it happen.
- TODO: Profile the brick destruction; I’m concerned that this method will create a bunch of stale references to brickGoesBoom objects, since they may not be destroyed after they’re employed.
Adds score decrement for missed bricks

The score now decrements for missed bricks
I also added constants for the scores so I can change it easily.
