Aaron Wells (u-aaronw) wrote : Update reCaptcha library to use reCaptcha version 2

Google introduced reCaptcha API version 2.0 in December 2014. While they haven't announced a deprecation date for reCaptcha version 1 yet, we should upgrade our system anyway, because the version 2 is a better user experience and more secure.

See https://developers.google.com/recaptcha/intro

Google's github repository has a reCaptcha 2 PHP library, so we should use that: https://github.com/google/recaptcha

If possible, we should do this in such a way that the usage of the reCaptcha pieform element doesn't change, nor do any of the configuration elements.
