Bug 33925: Improve translation of title tags: Serials

This patch updates serials templates so that title tags can be more
easily translated. Some templates have been updated for consistency as
well: Harmonizing page title, breaddrumb navigation, and page headers;
Adding "page-section" <div> where it was lacking.

To test, apply the patch and confirm that the following pages have the
correct title tags:

- Serials home
  - Serials search results
    - Subscription details
      - Subscription edit
        - Search for vendor
        - Search for bibliographic record
      - Subscription renew
      - Serial collection
      - Create and modify routing list
        - Preview routing list
          - View routing slip
      - Claims
      - Check expiration
      - With a subscription which has manual history enabled, click the
        "Edit history" link under the "Planning" tab.
     - Select multiple serial search results and batch edit
  - New subscription
  - Manage frequencies: Create and edit
  - Manage numbering patterns: Create and edit
