Added marker for Ws and Qs in Historical Discharge WQ charts. Therefore, the XYChartGenerator got two new methods addDomainMarker(Marker, boolean) and addValueMarker(Marker, boolean). The boolean parameters determine, if the marker should be visible or not. This is analogous to addAxisSeries(XYSeries, int, boolean).
