Google reCAPTCHA dynamic URL

Hey

Last week we got hit by a wave of fake registrations with a lot of bounce emails as the recepients were also fake.

So I decided to activate reCAPTCHA.
As we also have a lot of users from China I wanted to use recaptcha.net instead of google.com (which is Google’s official workaround to deal with the great firewall).

Instead of only changing it on my local installation maybe it would be great to make the reCAPTCHA domain configurable through the config file.

Is this something more people than me would like to see?
