An event is now raised at the window level of the DOM when a server request is started or finished.
Now sets the value on the model before doing a delta request to the server, in case that value is changed back to what it was before by the server (which was leading to the model not raising an event, and the UI not to change accordingly).
Now raises a datapublication:rowDrillDown in line with the standard data publication behaviour, enabling the loading indicator to hook into this event.
