Pause stream/video in the channel and video-list page
A simple script that check the page on twitch you're on and will simply pause the stream/video. If you're on a live stream page (twitch.tv/{username} with the stream in big) or a direct video page (twitch/videos/{videoId}) the video/stream will not be paused.
It's a quite early version so may be buggy, please contact me if there is a bug.
