Bug 13692: series link is taking you to just 800a instead of whole 800

Bug 13692: series link is taking you to just 800a instead of whole 800

This patch modifies the OPAC and staff client's XSL template for the
detail page so that series links based on a traced 490 tag use both
author and series title from the 800 tag.

To test you should have multiple titles in the same series with matching
490 and 800 tags in each record. Apply the patch and restart Plack if
necessary.

View the detail page for one of the series' titles. The "Series:" link
should link to a search which uses both series title and author.
Clicking the link should return the correct results.

Test both the OPAC and staff client.
