Bug 6294: {BIBLIONUMBER} parsing for SearchForTitleIn

Adds support for parsing of the biblionumber into the SearchForTitleIn system preference, allowing
external sites with APIs (like Facebook or Twitter) to do link-backs to the details page for the
title.

Sample code for implementing Facebook "like" links and Twitter "tweet this" are included on the bug report
