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

Fix a debug message

This will help reduce useless process wakeups

* Don't find playlist
* Fix a few bugs in notification plugins

Todo: find a way to get rid of this mostly redundant code and rewrite the XOSD plugin

Don't remove AC_PROG_CPP our headerfile and library checking macros depend on it. Unbreak configure.ac

* various improvements to our Apple Remote bindings by the original author of the inofficial API, Martin Kahr (martin at his surname.com)
