v1.1.0

• Read private 'useProductionNames' key from UFO lib. When this key is missing, it is implied to be True (same as the current default behavior): i.e. post glyph names are renamed based on public.postscriptNames if present, else uniXXXX names are auto-generated from the glyphs' unicode values.
  If the key is set to False, then the post glyph names are not modified (#186).
