TypeError: merge is not a function

Now following error is displayed when npm start is called. Because webpack-merge changed the API.

$ npm start

> ***@1.0.0 start ***
> webpack-dev-server --progress --colors --config webpack.dev.js

***/webpack.dev.js:16
module.exports = merge(common, config);
                 ^

TypeError: merge is not a function
    at Object.<anonymous> (***/webpack.dev.js:16:18)

We need to add {} outside the definition of merge.
