This commit restores support for freezing or speeding up physics sims. Animate the "Speed" parameter under Domain->Time, which controls a multiplier factor for the rate at which the sim proceeds (i.e. the old "Fac-Tim" setting). Notes: * Subversion bumped to 4 to patch up defaults for new value so that old sim files will still run correctly * Names/descriptions could do with some tweaking * Porting this across was not that obvious since quite a bit of stuff had changed (as in, been cleaned up). However, from tests so far, it seems to work well.
