Bug 21345: Patron records with attached files not obvious from patron details view

This patch adds a section to the patron details page for listing files
which have been attached to the patron record.

To test, apply the patch and enable the EnableBorrowerFiles system
preference.

- If necessary, attach some files to a patron record by viewing a patron
  record and choosing "Files" from the sidebar menu.
- View the detail page (moremember.pl) for a patron who has files
  attached.
- You should see a new section under "Alternative contact" with the
  heading "Files."
  - Test the "Manage" button to make sure it takes you to that patron's
    files.
  - Confirm that all the attached files are listed.
  - Confirm that the links to each file work correctly.
