Scroll Wheel actions
I've noticed that the default control setup doesn't allow the scroll wheel to be binded to anything. IMO the wheel would be great to switch between weapons or spells.
Perhaps this should be a drop-down menu which will let the user select what the wheel does. Or by just letting it manually be set in the control options.
