Removed redunant calls in VisualiserRaceState.initialiseBoats().

Slightly refactored ResizableRaceCanvas - removed a redundant drawPoint() function, functions which alter the gc stroke call save/restore.
Text is drawn black, at 20pts.
The drawBoats() function: instead of drawing everything for each boat, one boat at a time, it draws the track points for all boats, then wake for all boats, etc..., to have better layering.
