Attach public key and encrypt by default

[Carolyn "Lynn" Knight-Serrano]

I have two feature requests/questions for notmuch-emacs? One would it be possible to add or configure in support for automatically adding your gpg public key to messages? Second, could there be a feature that checks if there's a gpg key for the recipient of a message and if there is, turn on encryption by default? Thanks!
