Smoke: Support for moving obstacles. (Merge from Smoke2 branch)

Sponsored by the Blender Development Fund.
http://www.blender.org/blenderorg/blender-foundation/development-fund/

Remarks:
The original code was not designed to support moving obstacles so I had to introduce some velocity constraints into the code to prevent smoke from exploding. If this causes problems with "fire" emulation, please let me know.
