Bug 31097: Display restriction types

This patch changes the display of patron
restrictions in checkout and patron details
pages to show the restriction type for each
restriction. It also changes the display so
each restriction is shown on a newline.

To test:
1. Before applying patch, set system preference
"PatronRestrictionTypes" to "Allow"
2. Go to Administration -> Patron restriction types
3. Add some restriction types, make sure you
fill out both "Code" and "Label"
4. Go to any patron and add one or more of each
restriction type
5. Go to that patron's checkout page
6. Notice that only the comments of the
restrictions are displayed
7. Apply the patch
8. Reload the page
9. Notice the restriction types are now
displayed correctly
