Title: Refactor and improve comments for custom captcha classes

Added doc comments that indicate the purpose of these copied classes.
Removed 'Zanata' from 'ZanataCaptcha' since it is redundant (it is already in a zanata package).
Refactored CaptchaResponseValidator to make isValid(...) more readable.
