Improve UI

Editing and managing the UI for Red October is troublesome because the HTML file is embedded in the main package as a string. Furthermore, the UI could use a bit of a style and organizational update. Additionally, it would be nice to be able to populate fields with query strings.

• Improve the structure of the UI so that more commonly used features (such as delegate) are prominent and administration options are hidden.
• Improve build process to allow the static assets to be edited as individual files and then packaged into the binary at build time. CFSSL uses the "rice" tool to do this.
• Allow the fields of the UI to be populated using query strings.
