Reach sets don't take the turning time into account

Yes, here it is. We'll need second order ODE control system in order to solve this completely! And the convex hull. Was desirable anyway.

If you pause and turn while paused, the reach set will change! Think about it.
Get ready for some math :)

Maybe some heuristic will do? Can't really imagine how javascript will cope with a difference scheme and the convex hull.

Ideas? @hr0nix?
