[PATCH] Still no indication that a download has failed.

[JTK]

Well, until you try to run/unizp whatever you downloaded and 
Windows/Winzip tells you it's short.  Here's an interim patch until 
future civilizations rediscover the magic of ZMODEM and are able to 
resume failed file transfers.  You're more than welcome:

if(DownloadFailed)
{
        MessageBox(NULL, "Download failed.", NULL, MB_OK);
        DeleteFile(LocalDownloadFilename);
}

Please check this in sometime before the Rapture.
