Renamed sharedModel module to racevisionGame - this is intended to be our single module program.

Moved Boat/MockBoat/VisualiserBoat into it.
Moved Polars, polarParser, VMG, and polar exception.
Moved the networking stuff into it.
Moved angle, azimuth, bearing into it.
Moved gpscoordinate into it.
Moved mark/compoundMark into it.
Moved leg into it.
Moved trackpoint into it.
