[FLASH-USERS] adding particle unit

[Slavin, Jonathan]

I'm adding both. It's for dust particles which need to know the gas
conditions (relative velocity, density and possibly temperature) at their
locations and then are subject to drag. So added a short range drag force
under Particles/ParticlesForces/shortRange/drag and an advancement method
under Particles/ParticleMain/active/dust

I think it may be working now (i.e. the setup), though I'm still debugging
the actual code.
