Subject: [PATCH 1/1] Put production bundle on a diet

Build was previously at a ridiculous 903,456 bytes.

Restructured config to have entirely separate production settings
without any hotloader stuff in the way, dropping it to 132,015 bytes.

This is still too big, as the app is just a production build of React,
11 small JS modules, and a CSS file, but it's a big improvement.
