Noah Campbell 74b55fc7c8 Normalize paths within hugo
filepath was used inconsistently throughout the hugolib.  With the
introduction of source and target modules, all path are normalized to
"/".  This simplifies the processing of paths.  It does mean that
contributors need to be aware of using path/filepath in any module other
than source or target is not recommended.  The current exception is
