2. File TestRipple2 in Apps is created to test the formfactor.
3. Unittests for the Ripple2 are created.
4. Functional test for the symetrical Ripple2 is created.

EllipsoidalCylinder and HemiEllipsoid commented out in StandardSamples.cpp

different implementation of getVolume() in FormFactorBox and FormFactorParallelepiped in order to be consistent with the other form factors
explicit addition of the special case q=0 in FormFactorSphere and FormFactorPyramid

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

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)

MSVC: switch to boost::time instead of linux time, RootMinimizers now compiled as static, switch to MathFunctions::isnan in functional tests
