[KPhotoAlbum] Breaking changes in file layout

[Tobias Leupold]

What about this one:

    QString Whatever::dbIdentifier(const QString &indexXml) const
    {
        const QFileInfo fileInfo(indexXml);
        const QByteArray bytes(fileInfo.canonicalPath().toUtf8());
        return QStringLiteral("%1-%2").arg(
            QString::number(qChecksum(bytes.data(), bytes.size(),
                            Qt::ChecksumIso3309)),
            fileInfo.dir().dirName());
    }

Gives me e. g. "60243-Fotoalbum" for my "/home/tobias/Fotoalbum/index.xml".
