Enables yalb premium buttons

/*
 * Enables buttons "change speed" without the need to login
 * Enables buttons "loop", "transpose +/-", "Download MIDI", "tuner" without the need for premium
 * "Download PDF", and Upload mp3 is currently not working

 How does this work technically:
 Well nearly all of the yalb-premium functionality is already there,
 what blocks it from been used is that the buttons at the UI (html-page)
 don't have the correct IDs or Class attribute.
 So later yalb just don't attach the corresponding handler to it.

 So the main mission here is the restore correct IDs or class attributes before
 yalb'S document_ready() event handler is executed.

 Hints for dealing with yalb.min.js:
 * search for 'create_google_tag' in the 'formated' JavaScript sources.
   It will bring you to all first level function of major interest
   and somehow compensate the missing comment and real function names because of the minified source.
   Example:
     create_google_tag("play", "user_id " + yalpB)
