Bug 16162: Making dictionary 'Delete' a button

EDIT: This patch should have gotten rid of those tabs
EDIT2: Will now apply with patch on Bug 16161

To test:
1) Apply Bug 16161 first
2) Go to Reports -> View dictionary
3) Confirm that the 'Delete definition' button now just says 'Delete' and is styled as a font awesome button.
4) Confirm that the button does not wrap on narrower browsers.
5) Confirm that column heading is now 'Action'.
6) Confirm that button deletes as expected. (If you're wondering about the missing confirm message upon delete, see Bug 16161.)
