Spam: The other white meat

Thanks to some help from joachim , I did some work to create an integration between the Audio module and XSPF Playlist. This means that if you have been using the Audio module to organize and play audio content, you can add in the XSPF Playlist module and the XSPF Audio module to get xspf playlists for your audio files. This is helpful if you are trying to to feed your audio files to a flash player for example.
