Now it actually sorts like version 2.3 was supposed to. Sorry about that. Also adds support for keeping tracks in album order even in multi-album lists. Thanks to Juergen Heisel for the fix. This is a minor bugfix release.
Speed is unchanged, but at least now it works much better.
It's a lot slower now. I rewrote the forking code and as a result you no longer get to set the number of parallel jobs. The shocking truth is that the necessity for that option was the direct result of ham-handed incompetence on my part in versions 2.1 and 2.1.1. Anyway, version 2.2 now optionally generates album lists in proper order, which will please a small but vocal minority of the users out there. In fact, fixid3 is hereby discontinued, since 2.0 is so damn cool.
