Refactored Race, MockRace, and VisualiserRace to use RaceClock instead of keeping their own timers.

Moved FPS tracking to Race class, so both VisualiserRace and MockRace can monitor their FPS.
LatestMessages is now observable. It notifies observers when an XMLMessage is received.
Boat now has StringProperty for name and country/abbreviation.
Moved the MockRace timescale value to Constants.RaceTimeScale. This is passed in to MockRace on construction.
Tidied up StartController.
Copied the visualiser's resources into the resources folder.
Refactored RaceClock. Added comments. Tidied code a bit. Moved to shared.model.

Started work on RaceController.
