[Feature request] Account for albums with more than one disc

[JRDetwiler]

Actual behaviour

• Albums with more than one disc (say, divided into two discs, e.g. songs 1-12 on disc 1 and 1-6 on disc 2) are sorted {1 1 2 2 ... 6 6 7 8 9 ...} in the album view.

Expected behaviour

• These albums should be presented sequentially as discs (e.g. {1 2 3 ... 12 1 2 ... 5 6}), at least as a setting, if not an assumed default.
• It's very nice that this app is one of the only on the entire Android market that can even sort by track number. Accounting for other metadata in song files would be very nice to have as well :)

Steps to reproduce

1. View any album divided into multiple discs.
