Add a mapNullable #60

It would be awesome to have a map that caters for nullable values and would return none if it's so.

At the moment I use

just(4).chain(x => fromNullable(add2(x)))

but it's cumbersome and not point-free. https://github.com/AlexGalays/space-monad implemented it in the map itself which imo is great.
