Restore RECAPTCHA_TESTING mechanism

[lenarother]

Hallo!

To make testing easier testing mechanism from django-recaptcha could be restored:

settings:
RECAPTCHA_TESTING = True
form data:
data['g-recaptcha-response'] = 'PASSED'

Currently it is necessary to mock verifying function
nobot.client.HumanCaptchaClient.verify

Thanks for the report!

I believe that RECAPTCHA_TESTING was a bad design choice and mocking together with proper documentation (which doesn't exist unfortunately) is a more correct approach particularly since there are multiple ways in which the verification can fail.

Another idea would be to write a testing related client implementation that can be used in the fields accordingly, e.g something like

class TestingCaptchaClient(ReCaptchaClient):
    def verify(self, challenge, response, remote_ip):
        return return RecaptchaResponse(is_valid=True, error_code=None)

Not sure yet what feels right, I'll look into it a bit more later this or next week.

Thank you!

How would you change client in test then? Should there be settings variable for that?
