This rewrites the implementation of ffmpeg-python. The API stays mostly the same, but with these changes it'll be a lot easier to add documentation and new features.
It adds sphinx to generate html documentation from docstrings, and gh-pages to host the generated documentation.
Documentation can be generated by running make html in the doc directory, and the gh-pages branch can be automatically updated by running make update-gh-pages.
I'll add more documentation for development/contribution soon.
