no prebuilt file in npm package

Hi @mdo @jonrohan ,
I'm a member of cdnjs team. We found that there is no prebuilt file been provided in npm package since v4.0.0. Is it possible to add it back? Thank you.

Does it help that you can build it with npm run build? Or does a CSS file need to be checked in?

We think that it would be better if CSS file can be checked in.
