Updated Freestyle API modules according to the new hierarchical package structure.

Additional bug fixes were also done along with the code updates:
* Fix for the use of old Interface1D.pointsBegin() and .pointsEnd() method names
in the definition of pyDensityAnisotropyF1D and pyViewMapGradientNormF1D.
* Fix for wrong data types (int instead of bool) for:
- pyChainSilhouetteGenericIterator constructor and its .orientation property in
modules/freestyle/chainingiterators.py.
- SpatialNoiseShader constructor in styles/external_contour_sketchy.py.
- ChainSilhouetteIterator constructor in styles/multiple_parameterization.py.
