Bug 31957: Improve translatability of text containing links on libraries admin page

The libraries administration page has several links to system
preferences that appear within sentences or with other text
around it. To make translations easier, we need to make sure that
those links don't break context.

To test:
* Activate IllModule (so we can see the ILL staff email setting)
* Go to administration > libraries
* Verify that the links for those settings show correctly
  * Reply-to
  * Return-Path
  * Ill staff email
  * MARC organization code
* Apply patch
* Verify links still work and show unchanged

If you are familiar with the process, you can also make sure
the strings now show up on po files as expected:
