[ADD] survey_dropdown_simple_choice

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.

+# survey_dropdown_simple_choice
+
+Ajoute une option « Afficher en liste déroulante » aux questions
+« Choix multiple : une seule réponse » des sondages : les réponses sont
+proposées dans une liste déroulante au lieu de boutons radio.
+
+Pratique pour les longues listes (pays, départements…).
+
+## Utilisation
+
+Dans le sondage, éditez la question → onglet **Options** → cochez
+**« Afficher en liste déroulante »**.
+
+L'option « Autre » (commentaire) et les questions conditionnelles
+fonctionnent comme d'habitude.
+
+## Limites
+
+- Si une réponse proposée contient une image, la question reste affichée
+  en boutons radio.
+- À l'impression et dans la revue des réponses (« Consulter vos réponses »),
+  seule la réponse choisie est affichée, ainsi que la bonne réponse pour
+  un sondage noté.
