Subject: [PATCH] Don't add comments to dist files via babelify

We've had some issues with different dependencies causing different results based on the environment,
which in turn causes unnecessary diffs - making our work harder to review.

Comments can be read through the ES6 source files, and through source maps when
generated through `npm run build --development`
