Support disc number id3 tag

By Ryan D.

When playing back a multi-disc album from a usb storage device, Sync does not use the disc number to properly order the tracks. It ends up playing track 1 from each disc, then track 2 from each disc and so on. Sync should instead play disc 1 in proper order, then move on to disc 2, and so on.

You can retag tracks so that disc one is 101, 102, 103 ..... and disc two is 201, 202, 203 ..... etc.

That's what I have done and it works great!
