configure.ac: disable warning for unused parameter, some restriction in widl detection (need SDK from winhq CVS)

Fix compilation for libvlc users

Next bugfix release should be renamed to 0.8.6

Use Artist/Title/Album meta data in vorbis. Feel free to add what's missing and remove duplicate stuff from this code

Make sure we remove the callback before quitting

* add the new icons by Simon Damkjaer Anderson <simondamkjaer@gmail.com>, so Trax doesn't need to bootstrap over and over again. Implementation follows later on

* don't add -Wall to the obj-C flags, as you'll get flooded with useless warnings and don't see the errors anymore
