The MPS does not log its Messages to the mutator in telemetry

[thejayps]

We should probably diligently log every message we send to the mutator, so we know exactly what information the MPS gave the mutator when we're trying to debug something. We could even wrap the Message protocol inside the Event protocol if it isn't too inefficient, with a new Message Event Marker (bit 7 is still free). The main thing though is probably to have 1-1 mapping of message content and log content, and both emitted one straight after the other.
