Squashed Particle System Stateful Rewrite

Add TargetAffector
Fix for ParticlePainter offsets
Adds a particleStates property to ParticleSystem
Augment SpriteGoal to change system states as well
Also add 'collidingParticles' list to affector.
Particle Stochastic States Now actually working, and you can put
emitters, affectors and painters inside their targeted state.
Fireworks example uses states instead of delegates.
Replaced the delegate example with a text thing.
The examples launcher now also contains all the custom examples.
Adds CumulativeDirection and working null Affector (for affected
signal).
Add spaces after all flow control keywords.
