Title: Added initWithFile method to CCParticleSystemQuad for sprite sheets

Added initWithFile method to CCParticleSystemQuad so that a sprite sheet may be used directly from a dictionary without extra code. This allows one to simply use a CCSpriteFrameCache named object in place of the textureFileName so that the particle texture is used from a sprite sheet, thus increasing efficiency of CCParticleBatchNode and CCParticleSystemQuad when different sprites are to be used but are all on the same sprite sheet texture.
