Changed getSaleOrderItemSmartList to getOrderItemsSmartlist

Hey Greg,

This may be something you'll want to check.  I changed the smartlist in the saleOrderItem tab from the getSaleOrderItemSmartlist  to getOrderItemsSmartlist as I was not able to access the saleOrderItemSmartlist within the panel.  I'm a little concerned about this fix as I was able to access the saleOrderItemSmartlist in the detailorder view (outside of a panel). 

I think I may be missing something.  What do you think?
