[bug #18134] Unable to drag an item inside another item in NSOutlineView

[Quentin Mathé]

Follow-up Comment #2, bug #18134 (project gnustep):

This feature isn't implemented by NSOutlineView, so it isn't really a bug
:-).

I have put in attachment an experimental patch that adds this feature. 
This patch implements full drop support modeled against Cocoa behavior and
corrects few existing issues related to drag/drop in NSOutlineView iirc. You
may want to try it until I submit a clean version that can be committed.
