Bug 10773 - Add item-level descriptions for Label Printing

This patch adds new fields ccode_description, homebranch_description,
holdingbranch_description, location_description and
permanent_location_description which can be used in the Label Creator
to display names/descriptions instead of codes

Test Plan:

1) Edit a layout in the Label Creator so that it includes any of these
fields. I suggest including "homebranch_description" and perhaps
"ccode_description" if you have them in your item data.
2) Add items to a batch in the Label Creator.
3) Export the batch using the layout, and view as PDF
4) Verify that you see descriptions for fields which you added
