FEATURE: upgrade to most recent klaro.js version

* now using most recent klaro version
* removed code for inline hints as klaro now supports contextual consents
* removed code for creating Js in PHP
    * PHP now only creates a json config
    * everything concerning Js is kept in the browser
* changed api/config to be closer to the klaro config
    * klaro now feels more mature ;)
* added a lot of documentation
