Fix For imports? Style Polyfill

[JohnPucciarelli]

I tried adding firebase to this boilerplate and got the following error when fetch was called.

Can't resolve 'imports?this=>global' in '.../node_modules/firebase'

I believe the offending line is here:
https://github.com/nicksp/redux-webpack-es6-boilerplate/blob/master/config/webpack.config.base.js#L27

Installing imports-loader and exports-loader resolved the issue. I.e.

npm i imports-loader exports-loader -D

I found this solution here:
