Subject: [PATCH] FIX: Don't set_wmclass on GTK3

The method is deprecated, and according to docs should just not
be used: https://docs.gtk.org/gtk3/method.Window.set_wmclass.html

The docs suggest gtk_window_set_role(), but AFAICS this is only
helpful if one want to place the window in a certain position
when restarting a session. I assume we don't want/need that.
