Integrated the CKEditor

#7 and #8: The class CMS_EDITOR generates javascript code that replaces a textarea with a wysiwyg editor. Only a few methods have to be implemented by the subclasses, for example by CMD_EDITOR_CKEDITOR. The class CMS_FORM_TEXTAREA extends WSF_FORM_TEXTAREA with features to include the javascript from CMS_EDITOR. The most complex usage is shown in CMS_NODE_TYPE_WEBFORM_MANAGER, where the textarea is only replaced if "full_html" is selected as the desired body format. This works dynamically on the browser side as soon as the user selects another format.
