fix Body.getVelAtPoint etc and (hopefully) Body.eachConstraint #9

BTW, I don't have any code to test .eachConstraint... in the C version I see func(body, constraint, data); but in your port it's func(constraint); -- should that be ? Gahhh, OO strikes again...


Nope, just func(constraint). The rest of the information will be available in the closure of func, because JavaScript is awesome and has closures.
