Use PIXI.ParticleContainer instead of PIXI.Container?

[belohlavek]

The ParticleContainer class is a really fast version of the Container built solely for speed, so use when you need a lot of sprites or particles.

We might want to consider using it as a default, because we're not using many of the advanced features we'd lose anyways:

The tradeoff of the ParticleContainer is that most advanced functionality will not work. ParticleContainer implements the basic object transform (position, scale, rotation) and some advanced functionality like tint (as of v4.5.6). Other more advanced functionality like masking, children, filters, etc will not work on sprites in this batch.
