sw doc model xml dump: improve undo-redo coverage:

- show the undo manager's node array
- show SwUndoDelete
- show SwUndoSaveContent
- show SwHistory
- show SwHistoryHint
- show SwHistoryTextFlyCnt
- show SwUndoFlyBase
- show SwHistorySetFormat
- show SwUndoInserts

When an action + undo pair goes wrong, it's easier to see the state of
the undo stack after the action this way, then decide if the undo stack
is already bad, or the problem is with the undo implementation.
