Proper error handling for nbformat versions in client code....

Proper error handling for nbformat versions in client code. 1. Users are warned when an older nbformat notebook is converted. 2. The notebook notifies the user when a notebook that is too new is attempted to load. To test these things, create a simple notebook. Then change its nbformat field by hand to 2 (to test 1) and then 4 (to test 2).
