Set default installable
Thus $ nix build -f foo.nix will build foo.nix. And $ nix build will build default.nix. However, this may not be a good idea because it's kind of inconsistent, given that "nix build foo" will build the "foo" attribute from the default installation source (i.e. the synthesis of $NIX_PATH), rather than ./default.nix. So I may revert this.
