Auto Detection. Application Icon.

Auto detecting ID3 tags works now! Hoorah! From what I can judge by
looking at Last.FM's API methods, there's no way for me to get the
song's track #, year, or disc #/disc count. I can get the number of
tracks on the album, but that would require looping through another XML
document to sum up the amount of <track> tags for the album. Last.FM may
return the album year for certain albums, but none of the ones I
manually looked at had the year tag.
Added in application icon. Can't see it too well, but it works.
Removed all references to GraceNote and LastFM-Sharp library since they
weren't being used.
Hid LastFM's fingerprint client so user doesn't see it running.
