* [DIR_EXT,EXT] Appending directories does not create a directory.
* [DOWNLOAD_LOD,FIX] Collection of status and messages is now done per file. It used to be the case that later files would not be processed if an earlier file would raise an exception.
* [DOWNLOAD_LOD,FIX] Resuming a partial download would append the same data twice. Now the previous attempt is first cleared remotely.
* [REMOTE_EXT,NEW] Added clear_remote_directory/1.
