Bug 33927: Improve translation of title tags: Tools

This patch modifies tools templates so that title tags can be
more easily translated. The patch also makes some modifications to
titles, breadcrumb navigation, and page headers in order to make them
more consistent with each other and with other similar pages.

To test, apply the patch and go to Tools. Test each of the following
pages and each variation of the page to confirm that titles,
breadcrumbs, and page headers look correct.

- Tools home page
- Import patrons
  - Import results
- Notices and slips
  - Main page
    - Main page filtered by library
    - New notice
    - Edit notice
      - Preview notice: With a CHECKIN, CHECKOUT, or HOLD_SLIP notice,
        fill in the "Data for preview" box in the "Email" section.
        Although the template loads in a modal window which doesn't show
        the page title, you can confirm that there are no errors.
- Overdue notice/status triggers
- Batch patron deletion
  - Confirmation page
- Batch patron modification
- Batch extend due dates
- Upload patron images

Print notices: With useDischarge enabled, log into the OPAC as a
user with no checkouts. Go to the "Ask for a discharge" tab and click
"Ask for a discharge."

Locate the patron's record in the staff interface and click "Discharges"
in the left-hand sidebar menu. Click "Generate discharge." Open the
resulting PDF file in a browser. The page title should be "Print notices
for [date]."
