[Gtk-sharp-list] Change background of widget using theme colors

[Christian Hoff]

Sorry, I didn't think enough when I was writing... If it really is 
against the rules, you should be able to connect to the StyleSet event 
using the GLib.ConnectBefore attribute and modify the background there. 
But I think it should work since the style should have been set after 
you invoked base.OnStyleSet
