This commit removes SimpleCaptcha::getForm() and replaces it by its more informative counterpart getFormInformation(), which returns an array, which provides some more information about the form than only the html. The information included in the array is: * html: The HTML of the CAPTCHA form (this is the same as what you expected from getForm() previously) * modules: ResourceLoader modules, if any, that should be added to the output of the page * modulestyles: ResourceLoader style modules, if any, that should be added to th output of the page * headitems: Head items that should be added to the output (see OutputPage::addHeadItems) Mostly you shouldn't need to handle the response of getFormInformation() anymore, as there's a new function, addFormToOutput(), which takes an instance of OutputPage as a first parameter and handles the response of getFormInformation for you (adds all information to the given OutputPage instance, if they're provided).
