Allow to create a production build

[arunoda]

Right now, we need to run storybook locally via something like npm run storybook. But, it'd be great, if we can build the final HTML and share it anywhere.

So it'll be something like npm run storybook-build.

Then it'll create a directory in your project and you can upload those HTML file to anywhere you want and share your stories.

I have a working version here. I'm not that familiar with webpack so someone should take a look.

This is implemented.

I found this issue looking for documentation, if this is implemented, can anybody post a link to the documentation? Thank you!
