* Hooking into the APIEditBeforeSave hook (which will appear in the ApiEdit_Vodafone branch in the next revision)
* Moved general CAPTCHA generation in SimpleCaptcha to getCaptcha()
* Moved general confirmEdit() functionality to doConfirmEdit() to facilitate differtiating between UI and API handling
* Adding SimpleCaptcha::addCaptchaAPI() method that adds CAPTCHA information to an API result array. Other CAPTCHA implementations should override this method with a function that does the same (did this for FancyCaptcha and MathCaptcha)
