remote stream recording and data-connection.js

data-connection.js updated; fixed many bugs.

remote stream recording experiment added; it is appeared that RecordRTC
is unable to record remote media streams....

Default codec used in RTCPeerConnection is opus...which supports both
"voip" or "voice" i.e. mono single channel audio.....and "audio" i.e.
stereo dual channel audio.

Stereo is the only supported format for WebM files...and is the only
supported format for audio recording using RecordRTC.

Other possible issue can be input/output audio channels aren't matching.
