Yet another album art script

This one is in ruby and a bit more minimal.  Takes artist and album, returns url.  Gets big art from itunes.

@TODO now do a separate script for finding albums in need of art and acquring it.
Update art for current cmus track

Identifies open track and updates its art with new rb script.

My instincts said to loop over all my art all at once.  That doesn't really make sense.  This was I can do it on demand and any new CDs that slip by without album art will be updated as needed.

This works very reliably.  Only one bad art so far and that's Mike Oldfield's amarok.  Not sure how much I care.
