1)Refactor example scene get debug draw.
2)Fixed android/ios builds. The dump function can't create a file on mobile.
3)[Breaking change] Refactor jointDef initialize method
-Make initializeJoint method for every joint in box2d. This method return joint def lua table.
function box2d.InitializePrismaticJointDef(bodyA, bodyB, anchor, axis) end
...
-Remove initialize call when create joint from table. In world:CreateJoint()
So you can use initialize method if you need it. Or not use it, and create table manually.
