Page with different captcha options get only the last option set

Hi Blake!
Single page with 3 forms
 - form1 captcha enabled
 - form2 captcha enabled
 - form3 captcha disabled
 
 Since we are setting and checking a single page variable, all forms will have captcha disabled.
```
// classes/MagicForm.php
$this->page['recaptcha_enabled']       = $this->isReCaptchaEnabled();
```
