Everyone please try out this patch to prevent character login duping. I
have confirmed it does work for the case where one person logs in and
answers 'Y' to "Are you sure?" The next login attempting to create that
name receives an 'Invalid name.' message. Test to make sure there is no
other possibility I may have missed.
