Order series in pivot charts

A new feature has been added for pivot charts – you can now override the default series order and customize it.  This can be useful when showing area/line charts where series are drawn ‘on top’ of one another.  You can control which one is on the top and which is in the back and so on.  See the new ‘Order Series’ button which opens a dialog where you can drag and drop the series in the desired order and save it.
