* Convert build to use a single JavaScript file on the site (instead
of downloading each library separately). This also means that all
global variables (e.g., `$` for JQuery, `_` for Underscore.js) can
be removed.
* Remove unused scripts and/or move them to a more appropriate repo
* Update the `deploy` script to work with CircleCI's automation
* Update markdown display code to allow images to be located with the
markdown data files instead of the pre-rendered index pages
