added explicit export list to Char.elm

When exporting a type alias, like KeyCode here, will the importing module "know" that KeyCode is Int, or will this be opaque from the outside?

As things stand, the outside module will know. I think this is the right way to go in the sense that you can do hiding with type KeyCode = KeyCode Int and we'll eventually do the same unboxing trick that OCaml and Haskell do (the newtype trick in Haskell)
