Simple but effective order split

I’ve asked Fahad to make a simple plugin to split orders. This one is very nice to have manual control over my backorder process. You select the products you want to split and a new order with the selected products is made. You can choose to delete the selected order lines in the original order. The customer can see what is happening on his/hers My account page with the order. A reference in the new (splitted) order is visible.
