New Feature: Edit Invoice for Multiple Shippers & Consignees

There is a new feature that allows you to edit how many Shippers and Consignees appear on the Invoice.  By default the first Shipper and last Consignee will always appear on the Invoice.  If you have multiple Shippers & Consignees on the Invoice you can add them also.  Just above the Generate Invoice button, there is a checkbox to take you to the edit page.
