Many of the question types in qanda.php (qanda_helper.php), like do_array_5point(), display  messages indicating whether the question is mandatory or has validation requirements (like min_num_answers > 5).
    Refactor those to use the tips from LimeExpressionManager::GetQuestionStatus($qid).
    Eliminate all database calls from qanda.php - all of the information they need to display questions, messages, etc. should be available from GetQuestionStatus($qid).
    Integrate these same tip messages into printable survey and data entry screens (so uses can see the relevance and validation logic even on the printed page).
