I want to be able to create a blogpost nodetype in the World Outline editing window.

The parent of this node is of type blogpost.

I made a very simple little change to the blogpost callback, if there is no url attribute, then we display the subs of the node.

So the procedure for creating a blogpost is as follows:

1. Create a new headline in the OPML Editor.

2. Choose Set nodetype from the World Outline sub-menu of the Outliner menu.

3. Enter blogpost

4. Save.

Obviously the blogpost renderer must be smarter. But for that I'm just going to copy the factor out the code from scripting2.root. We shouldn't have two big bits of code to render a blog post.
