template factories and template methods for ParticleSystem

[Hanmac]

hy I added commits to an extra branch that adds new template'd Factories for the ParticleSystem.
That removes the need to define the FactoryClasses yourself, so
addEmitterFactory(new BoxEmitterFactory) is replaced with addEmitterFactory<BoxEmitter>().
