Preserve timestamps

Browse Source 
Get timestamps from server for all downloaded files and set the last modified date to that.
Should also change timestamps for previously downloaded files when using single or multi threaded mode.
Retroactively changing timestamps doesn't work for files downloaded with --galaxy-install because Downloader::galaxyInstallGame doesn't try to download the file if it already exists and is the same file as on server.
