Article Creation Nesting
Link multiplication and more
When using the article creation wizard (a handy hidden function), while nested inside the data manager of another article, the links from the parent article are inherited by the wizard. Also, if this occurs when the parent article is a new article, the wizard inherits the parent's new thread data. In addition, such a parent is not considered an article by the DM, resulting in template usages to be improperly saved.
Fixed by clearing the parent thread data and cached links upon wizard initialization. Made the "article" flag less selective.
