It simplifies things if getPipeline handles creation and starting
of the revid pipeline. We don't need to be doing this in multiple
places.

When saving and loading manager state to and from file, we don't
need to worry about the slate exit signals. Now that we have
broadcast status i.e. "play" or "slate", we can derive whether we
need an exit signal based only on that.

For control requests, we only update aspects of the broadcast if
they have changed. Therefore, if the urls list has not changed
the revid pipeline is not updated, similarly if the status has
not changed, we don't do anything there.
This change modifies vidforward to accept multiple RTMP URLs in
its control request handler. This allows for the creation of a
revid pipeline for a mac with multiple RTMP outputs.
This change adds functionality for broadcastManager state save.
This is done by marshalling the broadcastManager and saving to a
file. Loading is performed by unmarshalling an re-populating a
broadcastManager value. Testing has been added for this
functionality. Other functionality has been added a side effect.
