Add "Hide on Contact" collision mode to ParticlesMaterial

Browse Source 
This can be used to make particles disappear when colliding, rather
than bouncing around or sticking to surfaces.

This is useful for rain particles which should not be able to go
through floors/ceilings, but shouldn't stick to surfaces either.
