Current FFRN Usage stats are now gathered from the map.
The Data gets paresed via the proxy.php and is promoted in the data section of the app objet.
Whenever an update is triggert (currently by polling) the getCurrentStats() fires the event 'usersupdated' right to the document.
TODO: Write a function to render the data, attach the render to the event
Only fire the event when the data has changed from the last poll.
This saves us some rendering time.
