Plumb the DragOperation through all the layers between the platform Drag-n-drop code and WebCore.

This allows the HTML5 DataTransfer effectAllowed and dropEffect properties to be set correctly in JS handlers, as per the HTML5 spec.
(The drag-dropeffect test isn't in WebKit yet -- it's part of a separate WebKit patch that's been in review for weeks.)
