Added GetOpt option parsing.
Take a '--continue' option, passed on to the downloader, which determines whether or not we attempt to continue a previous download.
Modified the downloaders to throw an IOError if the output file already exists and we're not continuing a previous download.
Print the external command used to execute Wget.
