Layout.navigation ignores styles

[altaic]

Not a big deal, but it'd be nice to be able to style Layout.navigation as implied by the type signature. Currently it simply ignores the styles passed in:

{-| Container for links.
-}
navigation : List (Style m) -> List (Html m) -> Html m
navigation styles contents =
  nav [class "mdl-navigation"] contents

I guess this is more about documentation. Trying to add styles leads to head-scratching, and, in my case, looking at elm-mdl's source; for others it might instead lead to frustration.
