Provide official support for Kurzweil screen readers

[darrinj]

Kurzweil screen readers are widely used, and it would greatly help to know that Canvas supports this product officially. This would help a great number of students, staff, and faculty to more easily access Canvas courses. I've started an Idea here: https://community.canvaslms.com/ideas/9722-provide-official-support-for-kurzweil-screen-readers" mod.... Continuing to widen access to Canvas can help us all.
