[Fontconfig] Announcing python_fontconfig

[Lawrence D'Oliveiro]

I have put together python_config
<https://github.com/ldo/python_fontconfig>, which is a Python binding
for the main parts of the Fontconfig API. The README gives some
examples of its use.

This can be used to go beyond the functionality of the Fontconfig
mini-wrappers in other Python libraries of mine:

* Qahirah <https://github.com/ldo/qahirah> -- my binding for the
  Cairo graphics library
* python_freetype <https://github.com/ldo/python_freetype> -- my
  binding for FreeType.
