paranoid_confirmation:eating

Add 'eating' (synonym 'continue') to the list of things that can be
set via paranoid_confirmation to require "yes" instead of "y" when
the user is prompted about something, in this case "Continue eating?".

dat/opthelp was missing a few of the paranoid_confirmation choices.
