switchStream, inactive-session, waitUntilRemoteStreamStartsFlowing, and TextSender.send.

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

-. added: connection.waitUntilRemoteStreamStartsFlowing = false;

-. added: connection.switchStream(session)
