making friction and elasticity a part of the individual physics objects for a dynamic object, not just one value for the entire body (although having one alue as a DEFAULT would be nice, but as it is this is more correct)
exporting destroy-game-object in case an object has any sort of special cleanup
converted demo to use new physics scheme: create-object with simple meta. works beautifully!! boxes are now described just like other objects, instead of having custom functions.
