[azaozz]

Shows when a term is both a category and a tag, also when a child category is converted to a tag and then converted back, restores the child status, if the parent still exists.

Let's test in trunk for awhile before adding to 2.5.

Take 2: converts categories to tags and tags to categories even if the term is both a category and a tag. When converting a category that is also a tag, adds the tag to all posts that are in the category and the other way around.

WordPress currently allows more than one tag with the same name if the slug is different. If there is a category with the same name too that is being converted to a tag, the converter will add the posts to the tag that has the same slug like the category.
