Freestyle Python API improvements - part 8.

* Proper handling of keyword arguments was implemented in Operators and ContextFunctions,
as well as in methods of Interface0D, Interface1D, Iterator, their subclasses, Noise and
IntegrationType.

* Operators' methods and functions in the ContextFunctions module were renamed from
CamelCase to lower cases + underscores.  Style modules were updated accordingly.

* Additional code clean-up was also made.
