 Bug 16048: Making notices actions buttons

EDIT: Adding no wrap class to Actions column for when libraries with longer names mess up formatting

To test:
1) Go to Tools -> Notices and slips (tools/letter.pl)
2) Confirm that all actions (Copy, Edit and Delete) now show as font awesome buttons and work as expected
