Remove discharge table scaling but add reference system to W - Discharge_Tables are now always W[cm] Q[m³] no need for special case handling depending on historical / master tables - W now has a referenceSystem value that can be CENTIMETER_AT_GAUGE or METER_OVER_REFPOINT. The default is METER_OVER_REFPOINT as this is the case for everything except the objects created from discharge tables Known issue: WINFO input validation is currently broken as it still scales the user input.
