Native FTP/SFTP support

[msharp]

I often need to ftp/sftp files from different locations.  Currently this is possible through Run Program(), but there are lots of challenges to this approach.  One of the biggest issues is there's very limited support to error check through the Run Program wrapper, say if a file hangs mid transport.  FTP can be tricky and a native FTP support would be a blessing.  Some common problems that it could provide: certificate acceptance on first connection, terminal set up, public key authentication, ect. (there's a mutlitude of log in problems).  It would also be convient to both pass commands and wait for prompts.

In one project I completed, I extract data from a SQL DB, use JSL to transform and analyze than save the results (files and reports).  We had to write a program is a different software that takes the files and sftp them.  I would have liked to accomplish the whol thing with JSL.  I run the process nightly use a .bat file and the task scheduler.
