avoid race condition when deleting/starting sessions...

avoid race condition when deleting/starting sessions javascript doesn't guarantee the order of AJAX requests, so we give `Session.delete` and `Kernel.kill` a callback signature. Changing the kernel type calls `Notebook.start_kernel`, which terminates the previous session, if defined, before starting the new one. A flag is stored, to prevent multiple simultaneous attempts to start sessions, raising a SessionAlreadyStarting Error, preventing the spec_changed event from firing.
