Added LatestMessages to network.Messages. This is an object that encapsulates the latest up to date set of race messages.

Race stores a reference to it. MockRace writes to it, and eventually, VisualiserRace will read from it.
Updated MockRace, MockOutput, Event to use it.

Angle now implements hashCode().
