A few fixes and a change to support a Floating Notifications music extension I am working on.
-Fixed issue where songs would always bookmark when the music service would shutdown
-Album art location is now broadcasted out along with the playing song information
-Bitrate is now estimated for M4A / ALAC files if the bitrate cannot be read from tags
-Fixed issue where sort order would not take effect until backing out and reselecting the item
-Fixed many of the album sorting options when "ignore prefix" is enabled
-Fixed crash when changing album art for albums that didnt have album art to begin with (caused by 126.96.36.199.. sorry!)
