Video Speed Controller - BETA Channel od ChadBailey

This addon is being offered as a way to make it more accessible for users to test the newly released firefox version of the existing open-source addon located at https://github.com/igrigorik/videospeed. The firefox fork of this addon can be seen today at https://addons.mozilla.org/en-US/firefox/addon/videospeed/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search but this is an unofficial fork, not based off of the main codebase. This effort is to combine the two into a unified codebase.
