Radio button alignment is awful on nominations review page (+nominations)

On a page like <https://launchpad.net/ubuntu/gutsy/+nominations>, the "Accept", "Decline", and "No change" radio buttons wrap onto multiple rows. This looks really bad, and makes it hard to tell which radio button is for which function.

This could be fixed by putting each radio button in its own table cell.
