cabal2nix and bitbucket? #250

I'm not sure if cabal2nix is supposed to work with bitbucket/mercurial. I'm getting the following output:

No, there is no support implemented for these VC systems.

Actually, this used to work, but was broken in 99e470e62f61913f1fe013b7ba7a71990d8c6672, because only nix-prefetch-git supports json output. Perhaps we should adapt the remaining nix-prefetch-scripts in nixpkgs to support json output as well?
