Enable notebook renaming
I prevented jupyter's default renaming behaviour that made API calls, to simply set the new name of the notebook.
And triggering the event. The name of the downloaded notebook is new_name.ipynb
.
Linked to #16
I tried to make my changes with the lowest footprint, adding the // [Basthon]
comment wherever changes occured without removing the original code (as seen for example in Notebook.prototype.save_notebook
).
