Bug 23543: Adding Withdrawn to the Item Search

This patch adds "Withdrawn" status to the item search form and item
search results.

To test you should have one or more items in your catalog which have a
'Withdrawn' status.

Perform an item search and limit to a widthdrawn status. Verify that the
search returns the correct results and that the withdrawn column in
search results shows the correct information.

Test the "Export results to CSV" button. The resulting file should
contain the correct data, including withdrawn status.
