Adds a reader to work with campusweb
This add-on changes two things on CampusWeb quizzes:
1) Allows CampusWeb exam text to be pasted off of CampusWeb into screen readers for accessibility purposes.
* Currently, CampusWeb has extraneous text in the copied text that makes it difficult for those with screen-reader accessibility needs to utilize TTS services.
2) Injects a "Read" button in each question to allow CampusWeb questions and their potential answers to be read via speech synthesis.
