Added correct reference files for IsGISAXS06 tests after removing bug from IsGISAXS and BornAgain code

Added Fourier transformed 2d Gaussian; removed strange looking denominator in InterferenceFunction2DLattice.cpp; regenerated python API

The issue 506 is resolved.

PythonAPI now hanbdles pure virtual method automatically, so should be save to use pure virtual in our CPP interfaces
