Add multicast event module

This does 2 things when loaded:

1) All events are serialized and sent to the multicast destination.
2) Any serialized event received on the socket will be reconstituted into
   an event and fired on the local box

So, if you make another local event handler listen for the custom event from
mod_event_multicast "multicast::event" you will be able to react to events
on other instances of FreeSWITCH
