AccelFilterInterpreter: New Smooth Acceleration Feature

With this feature, the acceleration multiplier is determined by
averaging the previous three motions that connect to the current
motion. I.e., each motion's end time must correspond to the next
motion's start time.

This is especially helpful for pads that sometimes have uneven motion
(ie, short moves then long moves), so that the acceleration doesn't
multiply the difference between short and long moves.
