Bug 8550: Z39.50 searches for ISBN/ISSN problematic

Browse source 
Rather than treating ISBN and ISSN as the same, this patch breaks
them out into separate parts of the query, as well as changing
the truncation attribute to enable right truncation (the correct
behavior for the ISBN field in MARC21, and valid behavior in
UNIMARC).
