Send pageurl in 2captcha call

[fihzy]

Alert received from 2captcha.com:

We've found that you still don't send us the URL or the website where reCAPTCHA is being solved.
At the moment when we get the URL from the customer we forward our worker to the website where he gets the reCAPTCHA, solves it and then returns a token to us.
In cases when we don't get the URL of the website from you, we use a small exploit in reCAPTCHA to get the token. But our insider from Google notified us that the exploit will be fixed soon and it will be possible to solve reCAPTCHA only on the corresponding domain.

That's why we ask you to change the algorithm of your captcha upload and start to send URLs in your requests. This can be done with "pageurl" parameter. For detailed description of API parameters please refer to the page
