Cleanup JS, CSS and HTML

[Simyon264]

For JS, we could include a big "app.js" file which includes all the JavaScript needed.
For CSS, the same.
For HTML? Well, it's a giant mess of spagheti that keeps growing like Kudzu. I would nuke it out of orbit if it wasn't something I shaped with my own two hands.
