Bug 34402: Sorting holds on patron account includes articles

This patch adds some configuration to the table of holds shown on the
checkout and patron detail pages so that sorting by title correctly
excludes articles.

To test, apply the patch and clear your browser cache.

- Check out to a patron who has multiple holds on titles which include
  leading articles like "a" "an" and "the."
- Click the holds tab and click the "title" column to sort by title.
  - The titles should be correctly sorted alphabetically while ignoring
    articles.
