Spotify extension

This is a simple Spotify extension that displays the currently playing/paused song with artist and title. There are also some simple controls to pause/play, got to next or previous song and to exit spotify. Exit Spotify uses wmctrl which needs to be installed, or you can just remove the exit button from the script.

If spotify isn't running, "Spotify is not running" is displayed together with a button to start Spotify.
