component email gateway: add multicasting:
XEP-0033 multicasting is now supported both for incoming and outgoing messages. XEP-0033
metadata are converted to suitable Email headers and vice versa.
Email address and JID are both supported, and delivery is done by the gateway when
suitable on incoming messages.
