Experimental Loot 0.2

The money bag instability seems to have been caused, at least in part, by the fact it's a very soft object. The softness is now adjustable. A softer money bag (adjusted towards 0) behaves more like a soft cloth bag should, but may exhibit occasional instabilities. A bouncier money bag (adjusted towards 1) seems to be much more stable, but it behaves more like a medicine ball or a basketball.
