* Implemented Python's iterator protocol in Interface0DIterator and

orientedViewEdgeIterator.

* Simplified Python-related error handling in C++ class definitions.
The definitions of the following C++ methods were simplified and most
code segments using the C/Python API were moved to Director.cpp.

  ChainingIterator::init()
  ChainingIterator::traverse()
  UnaryPredicate0D::operator()()
  UnaryPredicate1D::operator()()
  BinaryPredicate0D::operator()()
  BinaryPredicate1D::operator()()
  UnaryFunction0D::operator()()
  UnaryFunction1D::operator()()
  StrokeShader.shade()

* Moved part of the introspection-based automatic type conversion code
from BPy_Interface0DIterator.cpp and Director.cpp to BPy_Convert.cpp
for the sake of better code organization.

* Fixed an uninitialized member in StrokeVertexIterator___init__().
