v8: use 4.5.107 by default Default v8 was fixed at 3.30.33, so running nix-build nixpkgs -A v8 would give us version 3.30.33, whereas nix-env -i v8 would install version 4.5.107. Now, both commands build 4.5.107, and there is still an option to install version 3.30.33 2016-07-23 18:17:13 +01:00			`{ callPackage, ... } @ args:`
