Message:

Emails: add List-Unsubscribe header to emails.

The List-Unsubscribe header is an optional chunk of text that email publishers can include in the header portion of the messages they send. In supported email clients, like some versions of Outlook, Gmail, and Apple Mail, recipients will see an Unsubscribe button they can click if they would like to automatically stop future messages.

Fixes #7390

Props chiragpatel, r-a-y.
