I had accidentally broken the raceXML construction - fixed it.

Fixed a few issues where boat didn't have nextMark/previousMark times under certain circumstances.
LatestMessages wasn't actually notifying properly - fixed.
The various XML readers now treat a string constructor as containing file contents, not file name - this was how it was mostly already used.
Fixed some issues in RaceXMLReader, including where element.getChildNodes() was used instead of element.getElementsByName(...).
Boat: changes speed to a doubleProperty. Changed leg to a Property<Leg>.
Race.lastFps is now an IntegerProperty.
Added breaks to the case statements in VisualiserInput. Whoops.
ResizableRaceCanvas now handles drawing the race boundary. Tidied up code a bit.
Removed ResizableRaceMap.

Started refactoring Sparkline. Currently doesn't work.
