Bug 19761: Move template JavaScript to the footer: Serials, part 2

Bug 19761: Move template JavaScript to the footer: Serials, part 2

This patch modifies more staff client serials templates so
that JavaScript is included in the footer instead of the header.

To test, apply the patch and test the JavaScript-driven features of the
modified templates: All button controls, DataTables functionality, tabs,
etc.

 - Serials -> Subscription detail -> Edit routing list
   - Add recipients
   - Save
     - "Save and preview routing slip" should trigger preview
       - In preview popup: Print and Close buttons should work correctly
