Port sendfile from KDELibs4Support
Review Request #117943 - Created May 2, 2014 and submitted
This patch removes all usage of KDELibs4Support in sendfile (src/sendfile). All string literals are also wrapped in QLatin1String/QStringLiteral. Use QCommandLineParser instead of KCmdArgs. It does not support --license and --author options now. There is one issue with native file dialog, QFileDialog::ExistingFiles mode (eg. select multiple files) doesn't work - it still allows to select only one file. It works fine with QFileDialog::DontUseNativeDialog option set to true.
