Capture all alternative titles

With the addition of bib browse, the alternative title index definition
was made to point at the 740 (ind2 != 2), which contains non-analytic
alternative titles /and/ non-filing indicator info.  It used to capture
both the 246 and (appropriate) 740's.  Allow either to match the XPath.

Replace inappropriate browse reingest with ...

... attempt at reingest across browse/facets/search but limited to
the alternative title index.
