Remove decorative alt-text from icons

    We noticed that when using a screen reader that the icons for exams have alt-text. In fact it seems that most of the icons under the Content area have alt-text. Since these are a visual decoration only it would make more sense for them to be hidden from screen readers. This would make the audible experience cleaner and less cluttered. We'd like to suggest that this change be incorporated for an upcoming release of Bb.
