Description:
[spotifywm](https://github.com/dasJ/spotifywm): Set Spotify's WM_NAME before opening the window.

Spotify does not respect window manager rules. Any window manager that try to apply specific rules like starting it on a determined workspace or maximizing it on startup, has no effect, as Spotify doesn't set the WM_CLASS property before creating the window.

This one should fix the problem.
