Google reCaptcha Support

Regarding removing the commented out reCaptcha code in Catalyst: #2578

We would definitely benefit from having reCaptcha supported in Catalyst. I've actually had one client specifically request it and I used the commented out code. Are there performance or security related reasons to not implement this code?

Barring some reasons not to use this code, please do officially support reCaptcha in Catalyst.

Thank you!

Thanks @pvaladez for the feedback here! This is exactly what we wanted to hear after having that code commented out for a while. I'll see if I can slot some time to get this worked on!
