Update nightwatch75/todo to 0.0.9 — drag-and-drop reorder (plugin API 5) (#91)

Manual-mode reordering now uses declarative drag-and-drop (ui.dragSource
/ ui.dropZone, plugin_api 5) instead of the two-click grip; also folds in
the 0.0.8 crash-loop fix (strike() gated on utf8.len) and an onExit
autosave flush. Translation keys nested for the validator.
