 Move Const to own module in Data.Functor.Const and enable PolyKinds

 `Const` from `Control.Applicative` can trivially be made
 kind-polymorphic in its second argument. There has been a Trac issue
 about this for nearly a year now. It doesn't look like anybody objects
 to it, so I figured I might as well make a patch.
