Bug 6553 - Parentheses in Corporate author break tracings

Bug 6553 - Parentheses in Corporate author break tracings

To test:

If an author's name includes parentheses or other escape-characters, the tracing links
produced in the OPAC fail in XSLT mode.  This patch wraps the author names
in double-quotes, providing the necessary escapement.

Test plan:
- Create a new framework, delete Thesaurus from 100 and other fields
- Create a new record in this framework (or change an existing record to this framework)
- Add 100$a - use parentheses
- Check the search links in OPAC detail pages
