... and use it for the Peer case class as specified in the ticket.

However, I'm a bit skeptical we want to go down the route of managing and materializing a separate source per actor. Instead I think it will be more practical to use one source with the messages from different peers. That way we won't need to worry about setup and teardown and precise synchronisation of these things. Look at the added spec for an example of this (there's a Thread.sleep in there.)

A possible improvement would be to materialize a future that completes when the subscription is performed (via ask-pattern with the PeerEventBusActor) to aid in this synchronisation. I was playing around with this but it only made sense for the specs, and I think we should avoid this kind of stuff for production code.

There's also a small bugfix in there to unsubscribe when the subscribing actor dies, which might cause memory leaks otherwise.
