Support buildHaskell

Use Nix and Briefcase to easily create Haskell executables.

I'd eventually like to support something like: briefcase.buildHaskell.project
that let me define a few top-level values (e.g. ghcExtensions) and would give me
a ghci environment with the proper `.ghci` settings so that my development
environment mirrored my build environment... baby steps, though.
