Merge lp:~parherman/dockmanager/spotify into lp:dockmanager

[Pär Eriksson]

I have written/hacked together a simple Spotify Helper (with much inspiration from banshee_control.py)

Right now it only supports Next/Previous and Play/Pause menu options, but i hope to extend it in the future..

Feel free to give me constructive criticism, as i have no idea what im doing!
