Bug 7097: HidePatronName not hiding on issue history

HidePatronName wasn't being respected on a titles Checkout History tab.  This patch
exports the preference to the template (if set), and then toggles the display between
patron cardnumber (if 'on') or the name (if 'off')

To test:

Enable HidePatronName
Go to the Checkout History tab of an item that has been checked out before
You should see the patron's cardnumber instead of their surname, firstname
