Show stats on Streamer page

Right now we show the stats on the Receiver page -- but this information would be a lot more useful on the Streamer page, where we are potentially doing P2P streaming to multiple different users.

I can work on this!

I started implementing this but ran into problems when trying to access "stats.video.recv" because the streamer is not receiving the data from the video feed. When #92 is solved this will be a lot easier to implement. Other than that the stats code from streamer and receiver are likely to be very similar so it might be beneficial to make this a component.
