publish multiple quizzes at the same time

When we import quizzes from another system we leave
them all unpublished so the teacher can review
the import results before publishing.  This adds
a "Publish Multiple Quizzes" button that will,
well, publish multiple quizzes -- at the same time.

fixes #3636
