Camera track and simulation

I have some problems with simulations: the bake button is not present. If anyone knows the answer please put it in the comments!

The camera track should also be improved because in most cases it puts in the console: "Some data failed to reconstruct (see console for details)" Put the camera track in full automatic as on mocha will be a luxury! I think we need to modify the tracker interface: put a selective menu like the modifiers: 3D, planar, and point. it will be clearer!

I also had bugs on the bones. For the connected to the meshe. Thanks for fixing it all !!
