Audon Audio Chat based on the WebRTC Addon

This Addon based on webrtc. Audon is a service of realtime audio chat.
With small changes, the WebRTC addon could be adapted to Audon so that it can be loaded into an iframe. In the ifram, the Friendica handle can be connected and a room opened. Audio conversations between Friendica users are possible.
