Migrating from security@ipython.org to security@jupyter.org

We have deprecated security@ipython.org in favor or security@jupyter.org ([internal discussion](https://github.com/jupyter/cve/issues/39)).

Emails received by security@ipython.org are now automatically transferred to security@jupyter.org, however we should gradually remove all occurences of the old email addresses.

However many occurrences remain.

Here is a small script to find them.
