Bug 28007: Replace obsolete title-string sorting: Tools templates

This patch modifies several tools templates to replace the use of
the "title-string" DataTables sorting method with the newer "data-order"
attribute.

To test, apply the patch and view the following pages to confirm that
columns containing dates sort correctly when using any setting of the
"dateformat" system preference:

- Tools -> Access files
  - You must modify koha-conf.xml to uncomment and populate the
    access_dirs section with a path to a directory containing some
    files.
- Tools -> Calendar
  - Test the date sorting in the "Exceptions," "Yearly - Repeating
    holidays," and "Unique holidays" tables.
- Tools -> Inventory (I wasn't able to test this because of Bug 28015).
- Tools -> News
- Tools -> Notices
- Tools -> Batch patron modification
- Tools -> OPAC problem reports
  - You must enable the "OPACReportProblem" system preference and submit
    some problem reports from the OPAC.
