switchStream, inactive-session, waitUntilRemoteStreamStartsFlowing, a…

…nd TextSender.send.

-. support added: inactive at initial handshake
-. E.g. connection.session = { audio: true, inactive: true }

-. added: connection.waitUntilRemoteStreamStartsFlowing = false;

-. added: connection.switchStream(session)
-. e.g. connection.switchStream({ screen: true, oneway: true }); //
remove all old streams and add screen in oneway.

-. fixed: TextSender is unable to send array.
