Email anonymizer

[lukeledet]

Add an option to receive emails from the public. The email address shown will be something like 15fd7b6681f9798e@noladex.org that will redirect to the user's real email address.

This would make a lot more sense for a user to want to add their email address as a main link if they knew it would by anonymized, but still allow for contact.
