[Proposition] Add unfolds for types.

[Heimdell]

I tried to code some isometric landscape generator (using svg) lately, and I got a task to solve: generate list of points (Int, Int).

The core.List module only contained List.range : Int -> Int -> List Int method. And no unfoldr or alike.
So I had to break my stream of thinking of things I want to do and implemented it myself.

My proposition: add unfold{r,l,} for any module describing "sequental container" types like List, Maybe, etc.

For instance, List.unfoldr : (seed -> Maybe (a, seed)) -> seed -> List a.

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
