v1.4.0

• Feature: Browser accepts ConnectorInterface and deprecate legacy Sender
  (#76 by @clue)

  If you need custom connector settings (DNS resolution, TLS parameters, timeouts,
  proxy servers etc.), you can explicitly pass a custom instance of the
  ConnectorInterface:

  $connector = new \React\Socket\Connector($loop, array(
      'dns' => '127.0.0.1',
      'tcp' => array(
          'bindto' => '192.168.10.1:0'
      ),
      'tls' => array(
          'verify_peer' => false,
          'verify_peer_name' => false
      )
  ));
  
  $browser = new Browser($loop, $connector);
