     Creates a new DeclarativeMimeData by cloning the QMimeData passed as parameter.
     This is useful for two reasons :
         - In DragArea, we want to clone our "working copy" of the DeclarativeMimeData instance, as Qt will automatically
         delete it after the drag and drop operation.
         - In the drop events, the QMimeData is const, and we have troubles passing const to QML. So we clone it to
         remove the "constness"
 
     This method will try to cast the QMimeData to DeclarativeMimeData, and will clone our extensions to QMimeData as well
