QuestyCaptcha lacks a hook to use different questions than what are randomly chosen from $wgCaptchaQuestions
Change 175389 abandoned by Florianschmidtwelzow:
Add hook to change Question outside of QuestyCaptcha
And anyways, Questy should have that ability built-in rather than a separate extension.
@leucosticte: Do you want to work on this? I abandon this change, just to clear up the code review list.
