Subject: nix-env/nix-instantiate/nix-build: Support URIs

For instance, you can install Firefox from a specific Nixpkgs revision
like this:

  $ nix-env -f https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz -iA firefox

Or build a package from the latest nixpkgs-unstable channel:

  $ nix-build https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz -A hello
