* First commit merging 2.4-based sim_physics in to volume25 branch.

Integration is still very rough around the edges and WIP, but it works, and can render smoke (using new Smoke format in Voxel Data texture) --> http://vimeo.com/6030983

More to come, but this makes things much easier to work on for me :)
