Subject: [PATCH] Experiments in kart drifting and stopping, please test to
decide. Added penalization to drifting, so it reduces engine power and
players stop abusing it (AIs would need the same limit). Added logic to
engange full brakes so the kart can be stopped if there is no power applied
and the speed is low.
