Sails are displayed on first boat in a race. Optimised imports.

- Implemented drawSails method
- Sail position is displayed and updated using a boat's heading
- Sails conform to 'Points of sail'
- Javadoc'd new method and tidied up existing
- Sped up track point frequency (visualiserBoat class)
- Optimised imports (any other classes changed)
- A lot of canvas drawing and sail rotating issues were discovered and eventually overcome along the way. Using a sail image to draw and rotate on the existing canvas rather than a JavaFX shape on a new canvas was the final decision.
