The original ErgFilePlot code used local static variables to bridge between the selected ErgFile and the Qwt data handlers. This was not an issue when we only allowed one chart of this type to be available at once. But now, with a more configurable layout it is possible to have multiple. The currently selected ErgFile can now be referenced from MainWindow in the same manner as the current RideFile can. This patch introduces no functional change for users.
