Subject: [PATCH] Show the signaling state and ice connection state in AppRTC
 by hooking up the peerconnections .onsignalingstatechange and
 .oniceconnectionstatechange events.

Hopefully this will increase the quality of the "it does not work" reports from users by giving them more information about what is going on under the hood.
