Major refactoring of the Notebook, Kernel and CodeCell JavaScript.

Browse Source 
* Kernel doesn't depend on Notebook or CodeCell.
* CodeCell doesn't depend on Notebook, only Kernel.
* All of the kernel management logic has been moved out of the
  Notebook into the Kernel.
* Public methods of the Kernel (execute, complete, etc) take
  a callbacks object that registers the callbacks for that msg.
