Fixed Twitch.TV Archive Videos, but broke toggleControls for it in the process. Also removed Justin.TV Support as it is now defunct and attempted to fix Twitch.TV Players' Volume issues.

This bit needs to be reverted before I'll accept these changes. Since the volume is out of 50, this won't work as intended. People also often complained about the volume being too low. I set it to half volume so it wouldn't be too loud or too quiet.
