This patch adds the syspref TraceCompleteSubfields. When TraceCompleteSubfields is set to "force," clicking on links in non-authority controlled subject tracings will only find other records where the entire subfields match. Leaving it at "don't force" keeps the current behavior of doing a keyword search of the subject indexes. This patch implements complete-subfield subject tracings in MARC21 XSLTs (OPAC and Staff) and all Normal mode interfaces. UNIMARC XSLTs have not been updated. This patch also adds the syspref UseAuthoritiesForTracings. When set to "Do not" tracings in the XSLT detail displays will never generate links using authority numbers, but rather use the heading strings (NB: the tracings currently use only subfield 'a' for generating links).
