[Haskell] JustHub 'Sherkin' Release

I am sorry if I gave the impression that JustHub was unique in adopting a
functional 
philosophy to distributing Haskell -- obviously it is not and that was poor
phrasing on my part.

The key feature is the way it integrates the multiple tool chains into a
single virtual tool chain with
a sandboxing mechanism provided by the hub hackage.

I think the Nix distribution might be a natural fit for 'hub' integration --
I would be happy
to work with the Nix people on that (though it can't be right now).
