Add support for CAPTCHA requests

[GoogleCodeExporter]

After registering new account at yandex.ru, I can't login to it via Vacuum-IM, 
in xml log I see that Yandex want to show captcha:

  <failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl" to="user@yandex.ru/Vacuum-IM">
    <temporary-auth-failure captcha_url="http://i.captcha.yandex.net/image?key=109v1lLlb0XxctcFERkEm0gMXJz6r06m" captcha_id="109v1lLlb0XxctcFERkEm0gMXJz6r06m"/>
  </failure>

Can you add support for entering captcha?

Seems that this issue is specific only to Yandex Jabber servers, because other 
Jabber clients didn't see this captcha request too. I report to his support 
this problem too.

It seems that yandex uses not standard captcha requests, but I can login with 
out any problems and captchas.

Sems that this is temporary problem with Yandex, after I write this problem to 
support, I didn't see captcha requests.
