LogsDownloaderWorker: Testing reusing FTP client for file listing when host and port change.
LogsDownloaderWorker: WIP trying to reuse FTP file listing clients in download.
LogsDownloaderWorker: Better error output when connecting to FTP server.
LogsDownloaderWorker: Better no connection to FTP server error avoidance.
LogsDownloaderWorker: No need to force getClient().changeWorkingDirectory(..) prior to list the files. Is better to ask to listFiles(..) with the path as argument.
LogsDownloaderWorker: Fix deletion of empty log folders from server while listing.
LogsDownloaderWorker: Fix partial download size indication.
LogsDownloaderWorker/GeneralPreferences: From tests partial download seams ok, but due to some on mission problems it will be disabled by default for now (still is possible to enable it in the preferences).
