Negative Scoring Limit

Here's another feature that I've just added to the Alpha - it effectively sets a minimum score of 0 for Partial Credit questions by default.

Say you have a question that includes negative scoring, but you don't want to allow an overall negative score to be offset against other scores in the quiz - you'd leave this switched off. If you want to discourage guessing so that a wrong answer on one question will offset a correct answer in another section, switch it on.
