Randy Heit bdd3188897 - Added support for horizontal mouse wheels, and set invprev/invnext as 
default bindings for it. (Only works with Raw Input on XP. Vista has
  support through Win32 mouse, as well. DirectInput does not support it at
  all, because the DirectInput mouse device does not expose this control.)
