Add Pandas PyCON/ SciPy video links to official documentation
I had learnt a lot from some of the videos like Wes' talk on Pandas for timeseries.
Some of the ones i have viewed and are not found on official docs
- http://pyvideo.org/video/696/pandas-powerful-data-analysis-tools-for-python
- http://pyvideo.org/video/611/data-analysis-in-python-with-pandas
- http://www.youtube.com/watch?v=0unf-C-pBYE
- http://vimeo.com/53065093

I am sure more such stuff is not yet linked
