Game slows down on low FPS #16

The idea of async update and render was to resolve the issue, but now it seems it simply doesn't matter, and the phys engine uses fixed constant for time calculation (which is silly, I know). May it's time to work on that...

One way to tell is, on low FPS, legs move quickly (sprite anim) but the actor doesn't actually move that fast.

You slide more on low fps: on Clear Ice, +3-4 blocks on FPS=70, +11-12 blocks on FPS=20

The branch "delta_t_aware_phys_2" should resolve this issue. (a quick and dirty suboptimal solution of "just update several more", which works unlike my prev attempt)
