* Set depth of events and whether they need to be federated.
Set the depth of each new event to one greater than the maximum depth
of it's direct ancestors.
Add a flag to each event passing through the roomserver that tells us
whether the event needs to be sent over federation.
We do this by passing the name of the server to send the event as.
We will need this capability if we want to support vhosting as it is
not possible to tell from the event alone which server to send it as.
(The reason for this is that sometimes a event needs to be sent on
behalf of a different remote matrix server)
