Add overwrite option to Frends.HTTP.DownloadFile

I have a couple of processes that downloads the same file every day. I have to use a separate task to delete it if not I get an exception. Today I am making a new one of these and forgot to delete the file. So the process worked the first execution but failed on subsequent executions. It would be nice if it was possible to tell the download task to just overwrite the file so that downloading the file was one box, and not two.
