Back on Lindelë again

I've recently discovered the wonders of the Music Player Daemon, and so I've decided to move Lindelë away from a GStreamer based player to a mpd front-end. It will take some major re-writing of most of the backend code, but I think in the end the application will be simpler to manage. I can finally remove all the copy & pasted playlist writing and reading code. Most of the music management is in the mpd itself, so I just have to make the callbacks call the right mpd functions and update the GUI accordingly. Now if only I had time to work on it.
