Title: Add custom mailer SMTP headers (fix #147)

Feel free to tweak the custom tags set by each email, but this should close #147, allowing you to tag each outgoing Devise email.

If there are other email actions you want to track you should be able to override them from here as well, but these are the built-ins and the only ones I'm aware of.
