Changed the names of several properties:
FollowEmitter:
emissionShape->emitShape
emissionHeight->emitHeight
emissionWidth->emitWidth
Emitter:
particlesPerSecond->emitRate
particleDuration->lifeSpan
particleDurationVariation->lifeSpanVariation
maxParticles->emitCap
particleSize->size
particleEndSize->endSize
particleSizeVariation->sizeVariation
ImageParticle:
image->source
And stopped being silly in the example launcher.
Now has DataParticle (with model and delegate) and an ItemParticle
(which you just feed items manually). ModelParticle left for now for
damage control - it will probably just disappear someday.
