Set binary=True for mapfile file handling

The YAML library produces Python string encodings of unicode objects.
There's no reason to try and convert them back into Python unicode
objects just to save them with binary=False, because the files are
only read in to be passed into the YAML parser, which can handle the
unicode characters correctly.
