Don't autoplay when paused
When a stream is paused, the stream ending and hosting/raiding another stream causes the new stream to play. There is not an easy way to "stop" playback (it can be done, but you have to go to another page so that the player shrinks and gets a "close" button), and it is frustrating to suddenly have playback if you've stepped away for a bit (i.e. phone call, doing something away from the computer, etc.).
Either there should be a "stop" button in addition to the "pause", or pausing a stream should not start playback when the streamer raids/hosts another stream.
