Freestyle: Fix for iterations over 0D elements in the reversed order.

The revision is concerned with Interface0DIterator and StrokeVertexIterator.
These iterators can be generated by Interface1D::vertices_end() and
Stroke::stroke_vertices_end(), respectively.  These methods return an
iterator poinitng the next index of the last 0D element (i.e., iterator's is_end
property is true).  When the iterators created in this way are used with
Python's iterator protocol (e.g., in a for-loop), iterations over 0D elements
are automatically performed in the reversed order.  This functionality was
broken after recent revisions concerning Freestyle iterators.

Also made minor code cleanup (white space).
