Particles: Create a simulation state for every Particle Simulation node

Every Particle Simulation node has a name (or a path when it is in a node group).
This name has to be used in the Simulation modifier on a point cloud to see
the particles.

Caching has been disabled for now, because it was holding back development
a bit. To reset the simulation, go back to frame 1.

Currently, there is no way to influence the simulation. There are just some
randomly moving points. Changing that is the next step.
