Bi-directional authority enhanced bib browse

This functionality extends the work committed as the following set:

d2f4cac923668ff05854ffc9720cafe514b9b71c Link browse entries to authority record when possible
3eb616e56c82a5106e14f5a446f1d875015db7f0 Inter-authority linking

With this, we enhance the browse method to allow the return of authority-only
terms (that is, main entries not used by a bib record) if the authority record
from which the term comes is linked to another authority record via the
mechanism created by 3eb616e5, and that linked authority record is itself in
use by visible bibliographic records.

In order to accomplish this we:
 * extend normalization of both bib and auth records to allow a custom string
   to be used when joining parts of a term (for instance, joining subject
   components with " -- ")
 * cause authority headings to be including in the unique set of values
   captured by metabib.browse_entry during authority ingest
 * link authority-heading derived browse entries to their authority-indexed
   counterparts
 * extend the metabib.browse() stored procedure (and related) to inspect
   authority-linked browse entries
 * extend bibliographic-visiblity testing to cover those bibliographic records
   in use by remote-linked authority records.
 * generate browse links between headings found to be appropriately linked
   and bibliographically in-use and visible

The addition of this functionality will require, in the least, reingest of
all authority records, and would benefit from reingest of bibliographic
records as well, as ingest has been improved and extended.

Removing pullrequest since there's now a squashing-introduced issue to resolve, it looks like.

Putting the pullrequest back after replacing a mistakenly removed trigger. Force-pushed.

Here's my signoff branch, as this works when I test it (both with a new schema and with upgrade script applied to master schema): http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/senator/auth-only-bib-auth-browse-signoff

Not merging for now, to allow for broader review.
