Revit IFC Export must not use both, LoGeoRef 30 AND LoGeoRef50

[ChristianClemen]

City2BIM/CityBIM/IFCExport/RevitGeoIfcExporter.cs is a two step IFC export (1.Revit + 2. CityBIM Plugin adds semantics and Georeferencing), When LoGeoRef 30 is e exportet in the first step, the IfcMapConversion (LoGeoRef 50) must not simply beeing added to the IFC Export. Either set the IfcSite position to 0,0,0 XOR neglect IfcMapConversion. User should be able to choose.
