Working on wordPress.root

1. If I create a top-level headline without clicking on the New Entry button, the Save button should still work (it should correctly set the attributes).
2. Add support for appkey, some of the operations need it.
3. Categories.
4. Multiple level indents, paragraph-level permalinks.
5. Better icon. (Not sure how to edit the resources.)
