Bug 31730: Link to authorized value interface when an authval is mentioned in preferences

This patch adds links to the authorized value interface anywhere an
authorized value category is mentioned in a system preference
description.

To test, apply the patch and go to Administration -> System preferences.

- Check these preferences:
  Circulation -> ILLHiddenRequestStatuses
  Circulation -> BundleLostValue
  Circulation -> BundleNotLoanValue
  Circulation -> ClaimReturnedLostValue
  Accounting -> RequirePaymentType
- Confirm that the link in the description of each preference takes you
  to the correct authorized value category.
