Embed: WebRTC improvements:

- make webrtc obey autoplay = false; when video is paused, disable autoplay and vise versa
- silenced some unneccesary webrtc errors
- webrtc: pause player on stop, so that "stream offline" message is shown
- improved webrtc wrapper robustness
- more webrtc don't autoplay when paused
- when not yet connected during a seek, wait until connected and seek then
