SFTP simple Download Java with ScriptMaster

[Cabinetman]

Same comments as the upload basically.

There's some FTP code posted but here's a basic SFTP version. Feel free to correct me or add to it and post.

Some elements actually might not be needed or could be better written.

I'm not a programmer per se so be nice.....
