bug 2248 [2/2]: import item status display in search results

The in transit status now displays as such in the
OPAC search results.  In the non-XSLT version, the status
is checked only for bibs having 20 or fewer items to avoid
extra hits on the database during result set presentation.
In the XSLT version, all items are checked.

Note that because an item's transfer status is not
stored in the MARC record, the transfer status
has no effect when limiting a search by item
availability.  For a future version, the transit status
should be added to the Zebra index.
