Add POL vendor code to invoice line display

Purpose/Overview:

Enhancement request from Michigan State – We were thinking about the large Harrassowitz invoices which we hope to upload, once the EDIfact files are available.  It’s important to us to see the vendor code (not organization name).  With titles in packages moving around, there is bound to be some cleanup needed with the records.  We need a way to glance through the invoice looking for unexpected codes without opening each POL.

Scenarios:

1. Scenario:
   • Given user has created invoice line from POL
   • When Invoice line is displayed on invoice view
   • Then MCL table includes a column for Vendor
2. Scenario: 
   • Given user has created invoice line from POL
   • When MCL table includes a column for Vendor
   • Then each row is populated with the Vendor Code of the POL
