component email-gateway: first draft: Initial implementation of the Email Gateway. This component uses XEP-0100 for registration. Upon registration and subsequent startups, a connection is made to registered IMAP services, and incoming emails (in `INBOX` mailboxes) are immediately forwarded as XMPP messages. In the opposite direction, an SMTP connection is established to send emails on incoming XMPP messages. rel 449
