Dynamic Paint:

* Surface bake data is no longer recalculated every frame, but only when surface mesh has moved/transformed. Results in multiple times better performance on high resolution surfaces when using sub-steps or surface is still.
* Heavily optimized particle brushes when random particle size enabled. Up to 10x speedup with large radius particles.
* Added an additional "grid" space partitioning structure for surfaces.
* Added bounding box checks for brushes.
* Smaller overall optimization.
* Further OpenMP parallelization.
* Added physics tab link to modifier panel.
* Fix: "Point Density" texture cache wasn't properly updated. Brushes can now use Point Density textures as well.
* Fix: Paint dissolve resulted in black color.
* Fix: KD-tree checkups weren't completely thread safe. Fixes possible crash with OpenMP enabled particle brushes.
* Fix: When brush was set to use a specific material, it was saved incorrectly and resulted in potential crashes on next load.
