* remove useless definition of Constraint2D library
* Fix : getting the world of the constraint before having created it
* Make the GetStaticBody function return a ref
* Remove : Useless AddJoint Fonction and Update CreateJoint function
* Update PhysicsSystem3D because GetStaticBody return now a ref
* Oops
* Having done something with the 3D and i was needing 2D
* Add ConstraintComponent as friend of Collision and PhysicsComponent
* Update all the Get[Static/Rigid]Body function so they return a pointer
