Hi !

I've updated the google recaptcha method to the newest, coolest "I'm not a robot" version. Mainly I've changed captcha.py and also the captcha.displayhtml(..) calls.

I've never contributed to a repo like this so (1) perhaps you can help me to push it here or (2) you can pick code from https://github.com/chuycepeda/gae-boilerplate/blob/master/bp_includes/lib/captcha.py and look for captcha.displayhtml() calls to send only public_key argument at handlers.

Cheers,

Chuy
