Fixed TransferEdge

Changed default value of write.surfacecurve.mode to 0.
Added SplitClosedFaces to XSTEPResource/STEP. This is necessary for correct display of closed surfaces (such as a torus) in applications such as ProEngineer, SolidWorks, Rhinoceros. Tests changed in connection with changing tolerance. In test bugs/iges/bug23018 enabled writing pcurves.
