IM-1239 Royalty Calculation and Maintenance 

This Extended Solution to the Inventory Management and Accounts Payable modules creates a system of marking Inventory Items as eligible to receive Royalties, defining by Item what its Royalty Percentage is as well as the Vendor who will receive the payments, then writing royalty records to a new file as part of Sales Order Sales Journal update. Records in this file can be edited via a new menu option.
