Bug 25699: Add edition information to "Holds to pull" report

Added a feature that displays edition information of the book
together with title in "Holds to pull" report.

Edition information is fetched from "biblioitem" table
as "editionstatement" and transferred to template.

Those changes don't have performance impact as all tables
including "biblioitem" were already used and joined in this request.
