The CLI moved into a separate package: webpack-cli.

While walking through the tutorial i ran into error message saying "The CLI moved into a separate package: webpack-cli. Please install 'webpack-cli' in addition to webpack itself to use the CLI."

On page 43 of the book we should add this package to the installations.

Thanks for reporting this. I need to update the tutorial to latest version of Webpack. Will try to do it soon.
