Sanitize mouse wheel code.

Consistently pass the mouse wheel delta as a CFX_Vector through out the
stack. Whereas currently sometimes only the delta-Y value gets passed,
and it is sometimes passed as a double and sometimes as a short.

Along the way, encapsulate the CFWL_MessageMouseWheel class and clean
up some nits.
