Fluid simulation

You can now simulate liquid fluids such as water, oil, or honey due to the new fluid simulation capabilities added by Nils Thuerey with the sponsorship of Google Summer of Code.

The fluids can collide with static objects, be acted on by forces, and can initialize properties of the fluid such as initial direction, and viscosity; as well as allow fluid to flow in and out of the simulation domain.

Animateable time steps

• solver now supports animated time steps, gravity and viscosity, an example can be found here: http://www10.informatik.uni-erlangen.de/~sinithue/temp/fluid_timeanim.mpg
• for simulation time animation the time IPO of the object is currently used, for all three there should probably be new ipos in the fluidsim struct

Misc

• the fluidsim meshes now replace the original one. so modifiers now work with them (apply modifier, or edit mode still work on original mesh).
• changed GUI a bit, now displays an estimate of the required memory
• temporary simulation files are now removed if env. var. BLENDER_DELETEELBEEMFILES is not set or zero
• default output is to '//fluidsimdata/...'
• there's still a problem with redrawing (currently relies on a call to the derived mesh generation)
