📝 Doc: Set dev server to 127.0.0.1

When walking through the setup documentationn I was unable to access the dev
server on localhost:8080 on Mac OSX. I attempted to implement the
workarounds suggested at
webpack/webpack-dev-server#183 to no avail.
This change allowed me to follow the output of the webpack dev server
directly and see all assets from the browser.
