Fix for Bug 4532, Use include file for bibliodefaultview logic

Note that this new include builds only the first half of the
anchor tag (<a>). Because title and subtitle are output differently
on some pages, rendering of the second half of the tag is left
to individual pages.

Includes fixes for staff client templates.

Change to basket.pl fixes a bug wherein the OPAC's bibliodefaultview
preference was being checked instead of the staff client's.
