Integrate Rope Joint

[fizzl]

Please integrate latest version of Box2d and create an accessor for Rope Joint. The revolute joints are a bit wonky for ropes.

I would do it myself, but I'm a bit rubbish with JNI.

I vote for this

You may be able to use the forked repo ptekchand/AndEnginePhysicsBox2DExtension. The branch GLES_Box2D221 (6c6b0a6's parent is 8f98edd) does not contain the changes for the BuoyancyController (a25b77b to bdb32a5) which has been included in the GLES2 branch of the fork.
