New stuff - Bending springs for hair dynamics. Code cleanup & optimization - Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better. - Removed child seams, something better will come here too :) - Normal particle drawing data is now saved between redraws if the particles don't move between redraws. * For example rotating the 3d view is now realtime even with 1M particles. - Many random values for particles now come from a lookup table making things much faster. - Most accessed small point cache functions are now much faster as macros. - Lot's of general code cleanup. - Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)
