Bug 14612 - Overdue notice triggers should show branchname instead of branchcode

Bug 14612 - Overdue notice triggers should show branchname instead of branchcode

This patch adds the Branches template plugin to the overdue notice
triggers template so that the library name can be shown instead of the
branchcode.

Also changed: Updated page title to match the name used in tools menus.

To test, apply the patch and go to Tools -> Overdue notice/status
triggers.

- Select a library.
- When the page reloads, the 'Defining overdue actions for...' and
  'Rules for overdue actions: ' headings should show the library name
  instead of the branchcode.
