Refactor SpriteEngine out of StochasticEngine

Also add ParticleGroups which use only StochasticStates
Simplistic change for now, just to focus the API for the
particle system. ParticleGroup elements replace the particleStates
property on the system, and the term "group" is now used more
consistently.
