Bug 9695 - Use alphabet system preference on page used to browse patrons for patron card batches

When adding patrons to a batch for creating patron cards, the template
shows alphabet links for browsing all patrons. This patch converts the
hard-coded alphabet links to use the new alphabet system preference.

To test, go to the patron card creator and create a new batch. Click
"Add items" to pop up the window for browsing for patrons to add to the
batch. You should see a working array of alphabet letters which link to
patron search results.
