Move FileDownloader to its own module and create a new class for each download process
A suitable downloader can be found using the 'get_suitable_downloader' function. Each subclass implements 'real_download', for downloading an info dict you call the 'download' method, which first checks if the video has already been downloaded

- ratelimit: Download speed limit, in bytes/sec.
- retries: Number of times to retry for HTTP error 5xx
- buffersize: Size of download buffer in bytes.
- noresizebuffer: Do not automatically resize the download buffer.
- continuedl: Try to continue downloads if possible.
- noprogress: Do not print the progress bar.
- logtostderr: Log messages to stderr instead of stdout.
- consoletitle: Display progress in console window's titlebar.
- nopart: Do not use temporary .part files.
- updatetime: Use the Last-modified header to set output file timestamps.
- test: Download only first bytes to test the downloader.
