The captcha module provides several diffent kinds of captchas to protect other
modules like selfreg. One of them is Google's reCaptcha.

The Problem is, that reCaptcha brings its own input field. But every module
integration of the Captcha module shows a standard (useless) input field and
description. If you type the captcha into that field, the captcha fails.

For selfreg I made a simple hack: in action.signup.php I added:

  $smarty->assign('captcha_lib', get_class($captcha->getActiveLib()));

So now in the registration 1 template I can noch check, whether the Captcha uses
reCaptcha and I can omit the captcha input field or not.

But not only selfreg uses Captcha. I struggled to find such quick hack like this
for the formbuilder module.

Other ideas? I find reCaptcha a goog idea. But the integration lacks due to its
differences to the other captcha libs.
