Bug 9509 - batchMod.pl does not ensure each barcode is unique

Test plan:
1) Browse to Tools › Batch item deletion
2) Enter a list of barcodes, make sure you have at
   least one barcode listed more than once
3) Click continue
4) Verify the duplicated barcode shows up multiple times in the table
5) Apply patch
6) Refresh the page
7) Verify each barcode now displays only once
