The hacktionary .js file is basically just a number of named links. We could remove this file and simply make those links come from some env setting. The only things I see in it that we still need are:

```
    "mdn_url_html": "https://developer.mozilla.org/en/HTML/Element/",
    "mdn_url_css": "https://developer.mozilla.org/en/CSS/",
    "mdn_url_css_selectors": "https://developer.mozilla.org/en/CSS/Getting_Started/Selectors"
```

Which we could relocate to a better spot.
