Refactored mock.Event to work with MockRace.

Fixed the networking imports.
Race now keeps a reference to its Race, Boat, and Regatta data sources.
VisualiserRace can be provided with new Race/Boat/Regatta data sources during runtime. Currently it updates boundary and legs with a new RaceDataSource, and marker boats with a new BoatDataSource.
