This is a little bit more understandable than device numbers.
Unfortunately, hot plug is as flaky as before: udev reports the device
before it is ready. alsa-lib provides no event interface (that I know),
so we have to stick with udev for now though.

Also, alsa-lib is _not_ used to fetch the card name. In my opinion, the
udev vendor string is a lot better. Compare:
- "USB Device 0xccd:0x77" (alsa card name) with
  "TerraTec Electronic GmbH" (udev vendor), or
- "Intel ICH6" (alsa card name) with "Intel Corporation" (udev vendor).

Move googleimage search first, and enable it again but don't use eg filename in search query.
Move musicbrainz after last.fm, and don't try more than one way to find art, also do query once in 2 sec

If you get bad hits from googleimage album-art, please report them to me.

Didn't touch the os x interface code. I don't think I missed any core-code that relates.
