Remove transformation from FormFactorCrystal; transform Lattice and LatticeBasis instead of q for form factor calculations; rotate mesoformfactor also

Make FormFactorDecoratorMaterial owner of (transformed)material; updated python API; removed transformation from FormFactorCrystal::evaluatePol; clone IMaterials

MesoCrystal test is off, new fitting examples for spheres in a lattice and corresponding changes in visitors

Implemented automatic propagation of BornAgain version number via cmake. Version must be defined only in the file cmake/modules/BornAgainMacros.cmake.

Fixed some problems with ambient material not being initialized in diffuse form factors; added the final part of diffuse calculation for polarized mesocrystals

Completed creation of mess form factor that supports polarized calculations; refactor: remove spaces before public, protected, private

Moved some implementations out of header file; fixed ParticleCoreShell for matrix form factor creation

Merged form factor material decorators into FormFactorDecoratorMaterial (for both matrix and scalar materials); moved matrix evaluate to IFormFactor; removed FormFactorPol

Refactor: internally store material pointers in FormFactorDecoratorScalarMaterial instead of the refractive indices

Refactor: rename form factor decorators containing material information to FormFactorDecoratorScalarMaterial and FormFactorDecoratorMatrixMaterial

Refactored FormFactor chain: transformation now sits in Particle; wavevector scattering factor and scattering density reside in the same class (FormFactorDecoratorRefractiveIndex and FormFactorDecoratorMaterial for scalar and matrix scattering respectively)

Moved to LayerSpecularInfo for polarized calculations (removed MagneticCoefficientsMap completely); Xcode project adapted
