Paul Sokolovsky 9e29666bf9 py: Implement proper separation between io.FileIO and io.TextIOWrapper. 
io.FileIO is binary I/O, ans actually optional. Default file type is
io.TextIOWrapper, which provides str results. CPython3 explicitly describes
io.TextIOWrapper as buffered I/O, but we don't have buffering support yet
anyway.
