Version 3.8.1

Added a lot of fun stuff into this one. Set up the admin email array to allow for different admin emails based on score and the ability to customize the admin email's subject. I also created a special help page that links to documentation, contains the support widget, and the new system information widget.

Also, for the developers, I created 4 new hooks in the Quiz Creator class. I also added 3 new helper functions for working with the quiz_settings array.
