Bug 30438: Add select all/clear all buttons to invoices.tt

To test:
1. Apply patch
2. Have a bunch of invoices, some open and some closed.
3. Go to Home > Acquisitions > Invoices and do a search that will
   return you many of those invoices, some open and some closed.
4. Notice the 'Select all' and 'Clear all' buttons.
5. Try clicking 'Select all' on the Open invoices tab. All Open invoices
   should become checked.
6. Try clicking 'Clear all' on the Open invoices tab. All open invoices
   should become unchecked.
7. Try 5 - 6 again but on the Closed invoices tab.
