Refactored and moved RaceXMLReader to shared/dataInput.

RaceStatus can provide windspeed in knots in addition to mm/sec.
RaceDataSource now provides a list of participating boat sourceIDs instead of boats.
Added a RegattaDataSource interface.
Angle, Azimuth, Bearing and mutable - careful.
Boat has positionInRace.
CompoundMarks have an ID and name.
Marks can be moved (setPosition(...)).

Refactored Mock.Race, Visualiser.StreamedCourse, Visualiser.StreamedRace, into (shared) Race, MockRace, VisualiserRace.

VisualiserBoat has color.
Added xml and polar files into resources folder.
