reCAPTCHA localization

I suggest there should be an option for reCAPTCHA to be in a certain locale. I have a site using Bogo with multiple translations, and when having a contact form in different languages, the captcha should be localized as well.

As far as I understand, the reCAPTCHA can be localized calling

<script type="text/javascript">
var RecaptchaOptions = {
lang : 'fr'
};
</script>

before rendering for French (fr) for example. I think it would be nice to have the locale as an argument to the reCAPTCHA field in Contact Form 7 instead of having to fumble with php files, themes and whatnot.
