COMMIT ALL THE THINGS

* refactor JS (a lot)
* use a CSS framework (neat/bourbon), because CSS is hard
* up/downvote comments
* cleaner HTML
* HTML inclusion in JS
* SVG icons for reference, up and downvote
* basic i18n: english and german supported ootb
* lazy (because slow) client-side identicon generation (preview ability)
* removed website input field for no particular reason
* remove HTML.js in favour of a homebrew DOM manipulation tool
