[Playlist] XSPFResolver.com update

[Nathan Freitas]

Paul,

This looks great - nice work. Hope you can keep having cycles to work on 
this as I think its very important type of mashup.

With all your caveats noted, I still haven't been able to get this 
playlist I created to work:
http://www.cruxy.com:8080/lab/xspfview/KevinSmithNonCelebrityPlaylist.xspf

It's a bit massive, but I would love for it to be able to resolve. Any 
thoughts?

Best,
   Nathan
