The automatic fallback should really be configurable

Issue Summary

The automatic fallback feature suffers at least two flaws:

- it is not configurable: Math is the hardcoded default
- it tries to establish a TCP connection on port 80 to the reCaptcha verify server, which is not that great in terms of performance, and is very unreliable.

At the very minimum, I suggest adding a configuration option that would allow disabling this feature and selecting the fallback captcha.

Definitely, I think we have two options here....

  • Make the check to see if reCAPTCHA a toggle checkbox and the fallback feature configurable so that you could switch to something other then Math
  • Remove this feature entirely. I believe we put this in back when reCAPTCHA was quite new and was having troubles with the server load. I'm sure they have a decent server farm by now, so they should be okay.

Pushing to critical so that it gets in the next release.
