Nonce no longer working (+ how to fix it)

[sandrb]

Your current implementation doesn't work anymore, it now uses timestamp instead of a nonce.
Here's a fix for you (line 699):

  private function generateNonce() {

    $nonce = (string) time() + 15;

    return $nonce;

  }

and at line 588
$headers[] = "api-expires: $nonce";

The api-nonce header is no longer needed
