Propagate Beam and Detector polarization to DWBASimulation and removed all previously used polarized outputdata structures

Add polarization density to Beam and Detector with interface for passing the Bloch vector; added Beam and Detector polarization to DWBASimulation initialization

Implemented scattering intensity for DA, SSCA and IsISGISAXSMorphology strategies in case of beam polarization density and polarized detection

Replaced shared_ptr with scoped_ptr in LayerSpecularInfo (2); provided clone methods to prevent shared pointers
