The implementation in commit 182fe790c9 ("Add ability to undo
renumbering of dives") looks perfectly reasonable, but it depends on an
implementation detail: it assumes that the keys of the QMap are returned
in the same order in which they were placed there. Which apparently isn't
the case for some version of Qt.
With this commit we simply remember both the old and the new number for
each dive and therefore the order in which they are processed doesn't
matter.
