Schedules Direct JSON and XMLTV Python API

[essandess]

I wrote a Python API that makes Schedules Direct JSON API calls and wraps the results in an XMLTV EPG file: https://github.com/essandess/sd-py

You all are welcome to use this. I have it working and tested with EyeTV.

I use the the lxml library to make this code relatively fast and efficient.
