Bug 26289: Add missing variable definition to templates

This patch puts definition of the missing "searchid" variable into an
include file to be used by various bibliographic detail pages. The
variable is required by several JavaScript functions.

To test, apply the patch and locate or create a record with no items.
Open the labeled MARC view and choose Edit -> Delete record. Confirm the
deletion. The deletion should complete correctly.

Perform the same test with the detail view, ISBD view,  MARC view, and
items view.
