Title: [774849] Improve article feedback survey.

Changes the options available in an unhelpful article survey, make the
choices radio buttons instead of checkboxes, and make the textual
feedback mandatary for some radio button choices.

This doesn't actually provide any back end protection for these things. The
previous system didn't provide a way for the server to reject the survey, and
since this is not security related, I feel that it is fine to rely on Javascript
validation for this.
