Whitelist only lib for files entry in package.jsons

[spacesailor24]

    For npm whitelisting only `lib` , this will filter out `dist` form including in published lib. 

This will impact CDN as current CDN is configured to pick minified build through npm ( as per Greg info, I discussed with him last time ).

I personally like it, as it will reduce lib size , so users node_modules will be of less size ( by excluding minified builds) but we will need to configure explicitly CDN for 4.x.

until we have same CDN structure, we will need to whitelist dist as well so its not filtered, fix posted in above PR.
