Add support for MediaStream.clone() method

[warrenjmcdonald]

This method is very important for creating new streams from exiting captures, that can then be independently modified and used for new peer connections.

I will add it when I get some spare time.

Any updates on this?

It will greatly help me in order to add recording functionality into my software.

Might be possible after 5.0.2 release.

[hthetiot]

Can be done on 6.0.0 I think.

[hthetiot]

Can be done on 5.0.4+ since 5.0.3 support MediaStream (Native and Plugin)

MediaStream.prototype.clone = function () {
	return new MediaStream(this);
};

Done and tested
