Do not blindly overwrite files when saving
When reading the data files, compute a cryptographic hash of the file contents and store it. When saving the files later, ensure that the hash still matches the current file contents. If it does not, show a warning to the user and ask whether she wants to execute the merge tool. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
