bib record subject search terms: painstaking translation of BibTemplate to TT

the reference implementation I used is in
Open-ILS/web/opac/skin/default/xml/rdetail/rdetail_summary.xml starting
at line 93 as of this commit.

Only now that I've imitated the default skin's behavior exactly, I note
that the subject search links produced don't actually work on my test server.
Seems to be a local configuration issue though; will investigate.
