Bug 11941: Add link to patron lists from the patron home page

The patron lists are only accessible from the tools module, which is not
easily accessible when you are in the patron module.

Test plan:
Go on the patron home page.
In the toolbar, you should see a link to the patron lists.

NOTE: Tweaked button to a to get the click to work.
