missing functions on google play subscription response.php

[compelling]

I suggest you add this to subscription response.php, it's a good idea to check expiration and payment state for subscriptions :)

/**

• @return int */ public function getPaymentState() { return $this->response->paymentState; }

  /**

• @return int */ public function getExpiryTimeMillis() { return $this->response->expiryTimeMillis; }

  /**

• @return string */ public function getResponseText() { return json_encode($this->response); }
