Drag and Drop menu sort order

[fireproofsocks]

It would be nice if we were able to do a drag-and-drop sort order (i.e. emulate the functionality inherent in the resource tree). To do this effectively, we would need a modal window that listed ALL the results in the active folder. Without seeing all results, it's impossible to sort them. We implemented this very type of thing in Moxycart. The trick to getting good performance here would be to rely on the existing cache inside the parent folder: list only the pagetitle in a sortable list in the modal window.
