Update for 4D 21 LTS: enable Direct typing, add missing class property declarations. This showed 2 - so far undetected - bugs, for FTP Active Mode, setting the port could fail (bad property name), terminating the worker failed (wrong function name). Proves the advantages of direct typing...
This build also contains the renaming of 2 commands for SFTP (#9)
No update done for the precompiled rsync/curl binaries for Mac.
(if you need to use older versions than 4D 21 continue to use older releases, fitting to your version). Don't use the version compiled for 4D 21 LTS with 4D 20 LTS, it will fail.
