For issue #8, create a videos application to randomize videos in the playlist. This commit now adds a dependency to the Google Python GData library. The admin enters a playlist URL in the admin. Then the admin uses an admin action to synchronize the playlist with YouTube. This reads the playlist title and retrieves the video list from YouTube. The view function reads all the playlist objects to get the complete list of videos, then shuffles them up. The template generates Javascript to create a YouTube player with the shuffled list. A fixture is included for convenience and for the tests. I also committed a test tool I wrote to prove out this idea in case it is useful for future enhancements or experimentation.
