Display "Multiple choice: only one answer" (simple_choice) survey
questions as a dropdown list instead of radio buttons, per question.
The native radios are kept (hidden by CSS) and still carry the answer:
the dropdown only clicks them, so validation, conditional questions,
"Other" comment, auto-submit and AJAX submit are handled natively.
In review / print mode, only the selected and correct answers are
displayed. Native rendering is kept when suggested answers contain
images.
