Bug 18871: Make patron list name a link to view contents of list

The link is the same as the 'Add patrons' button in Actions dropdown,
but requires one less click, and makes finding the contents of the list
more obvious.

To test:
1) Go to Tools -> Patron lists
2) Create a patron list if you haven't already
3) Confirm that clicking the name of the list takes you to the correct
list and shows the expected content.
