Bug 36707: Links on itemnumbers in report should say "item", not "record"

Bug 36707: Links on itemnumbers in report should say "item", not "record"

This patch changes the labels on SQL report result links so that the
term "item" is used for editing or viewing an item.

To test, apply the patch and go to Reports -> Saved reports

- If necessary, create a report which will return biblionumbers and
  itemnumbers, e.g.

  SELECT itemnumber, biblionumber FROM items LIMIT 20

- Save and run the report. In the results, test the menus which can be
  triggered by clicking a biblionumber or itemnumber.
  - A biblionumber's menu should have "Edit record" and "View record."
  - An itemnumber's menu should have "Edit item" and "View item."
