The sections are created on the edit quiz page, and then appear in the navigation panel when the quiz is being attempted to help students find their way around. The 'Shuffle questions' setting has been moved from being per-quiz to being a per-section. This commit is actually the joint work of Mahmoud Kassaei and Tim Hunt from The Open University. We could only use one persons name for the commit and this time Mahmoud gets the credit/blame.
