Add gear jiggle physics back as an option

I'd gladly sacrifice a frame or two for the jiggle physics to be back. Not everyone will, and that's why it should be an option in the graphics menu. Maybe with a high and low settings, where the high setting applies the jiggle physics to ragdolls as well. I really liked this addition back in the day and am sad to see it gone. It adds subtle secondary movement to the animations and it looks great.

It was never about GPU performance (maximum framerate) but about CPU performance (frame pacing, or stutter).
Besides the way it was done was unrealistic and simply put, looked bad.
