Added autoloading of CSS files.

Added autoloading technique of CSS files from
www.ethanjoachimeldridge.info/tech-blog/autoload-harp-css-js

Added a unused global variable so I can remember how to use the
environment later on when I need it for auth tokens to an API and etc.
Though really what I should do is do javascript encryption + nonce like
brain tree does with an asymetric key.

Moved CSS for statistics into it's own file. gosh that's SO much better
having that autoloaded in that way.
