JFonS 85ce4a67ed Remove animation loop from ParticlesMaterial + improvements to CPUParticles2D 
Remove animation loop from ParticlesMaterial and move it to
SpatialMaterial for 3D particles and Particles2D for the 2D case.

Added animation to CPUParticles2D as well as the "Convert to
CPUParticles2D" to the PAarticles2D menu.
