0030582: Coding - avoid defining references to properties of NULL objects

Browse Source 
Approx_SweepApproximation::Perform() now creates empty arrays.
GeomAdaptor_SurfaceOfRevolution::UTrim() - fixed No_Exception misuse.
StdPrs_ShadedShape - fixed defining an invalid reference to Poly_Triangulation::UVNodes().

BSplCLib::MovePoint() and BSplCLib::MovePointAndTangent() now take optional
weights parameter as pointer consistent to other methods like BSplCLib::BuildEval().
