LP#973666: Print Purchase Order does not print PO Name

Printing a PO from the menu option "Actions-->Print Purchase Order"
generates a document that displays the PO #, but not the PO Name. It
was suggested that it would be helpful if the print document
displayed the PO Name instead of, or in addition to, the PO #. This
commit adds the PO Name in the default template for new installs,
but does not affect upgrades.
