Clamp objects min/max velocity. Accessed with bullet physics from the advanced button with dynamic and rigid body objects. - useful for preventing unstable physics in cases where objects move too fast. - can add linear velocity with the motion actuator to give smooth motion transitions, without moving too fast. - minimum velocity means objects don't stop moving. - python scripts can adjust these values speedup or throttle velocity in the existing direction. Also made copy properties from an object with no properties work (in case you want to clear all props)
