Added functionality to edit existing quizzes. Added a done button. Added a way to edit quiz name.
Added support for sessions. I wasn't able to get any kind of "save all" working. When I put it all
in one form it caused the loop to print all the questions on one page. Also I added some basic
checking to make sure the user actually owns the quiz before they can edit quizzes, delete questions
or save quizzes. This probably needs to be converted to however we are doing permissions. Currently
the delete function is not working. This is due to the models not properly deleting. This can be
fixed by updating the database or the models. Also there is currently no validation of any kind.
