Added additional async support

For me It would be very interesting :)

Do You support video download cancellation of Async process? Unfortunately current release does not do it(but supports DownloadProgressChanged).

                // Register the ProgressChanged event and print the current progress
                videoDownloader.DownloadProgressChanged += (sender, args) => backgroundWorker1.ReportProgress((int)args.ProgressPercentage);

                backgroundWorker1.WorkerSupportsCancellation = true;

                // Run video downloader async. 
                backgroundWorker1.RunWorkerAsync(videoDownloader);

Gennady-G, you can cancel the download in DownloadProgressChanged. Set e.Cancel = true.

mysteryx93, thank You for reply! I encountered problems with it, described here:

Glad it works for You. I'll try again, maybe something has changed. Or it was my mistake..

Best regards,
