ACQ improved duplicate order detection

[Bill Erickson]

In Summary:

1. Detect duplicate PO names (for a given ordering agency) and warn the user during PO creation.
2. Display the number of catalog copies already owned at or below the ordering agency next to each lineitem in the PO interface.

Proposed specs:

Additions / alterations to the proposed spec.

1. What's not clear in the specs is that an option to apply/modify the PO name will now be present in the PO creation dialog. As before, it will default to the PO ID.

2. The statuses of copies to ignore in the existing copy count should be expanded to include: Lost, Missing, Discard/Weed, and Lost and Paid. Note that "copy_active" and other existing config.copy_status flags are a little too broad for this, though a new "count-this-copy-as-existing" flag is an option if needed.

We have tested this development and it has worked as designed.

Assigning back to 2.next for review during next development cycle.

Works for me! The duplicate PO check worked whenever I created an order under the same agency. If I created an order for another branch, no warnings were issued. It also successfuly displayed the number of live copies I already owned for a particular lineitem.

Signoff branch is available at:
