surveyEditor more or less works! Only needed change is addition of "topic" property in question objects (database-side), and the change from "category"(string) to "categories"(string[]).
surveyEditor still needs removal function and infofunction to be written properly!
Added all files belonging to SurveyAdvanced?. Most do not work properly yet, but at least there will not be a 404 page when you click btnPreview on survey.html.
