1489955: enable filtering authority search/browse by thesaurus
This patch adds support for restricting the scope of an
authority headings browse or authority record search by
thesaurus. For example, in SuperCat, the URL pattern
/opac/extras/browse/marcxml/authority.subject/1/heart/0/20
generates returns a browse of up to 20 authority records
centered around the subject heading "heart". With this patch,
the URL pattern
/opac/extras/browse/marcxml/authority.subject/1/heart/0/20/c
restricts the browse to MeSH headings. Multiple thesauruses
can be specified as well; for example, this URL pattern
/opac/extras/browse/marcxml/authority.subject/1/heart/0/20/a,b
browses in LCSH and LC Children's.
