AFM fonts and 'EncodingScheme' keyword

Hi Dominique,

Thanks for the fix. Could you send me your updated backend_ps.py. It
will be easiest for me to merge in your changes that way. Is it slow
for you to load backend_ps. If you have a lot of font files, I assume
it can take a while to parse them all. It might be useful to cache
this information in the way that ttfquery does...
