Enhancement: Add ability to create posts from Edit Order Screen

[acketon]

It would be really nice when building out a nav tree to be able to add new posts from the Edit order screen. Instead of having to do it the standard way. I think this would speed up data entry.

If you could have an option for a "new child page" in this menu:

and then redirect the user to the "Add New Post" screen with the Page order prepopulated that would be useful. Or even faster would be to click the "new child page" button, then show a field for Post name, enter the name of your post and create the post for them in that menu location without leaving the editor order screen. Then the user could choose to go work on that page, or keep creating "blank" pages to build out a nav section.
