Disconnect from an FTP Server

Demonstrates the Chilkat Ftp2.Disconnect method, which ends the FTP session and closes the control connection. It takes no arguments. When connected, Chilkat sends QUIT and then closes the socket.

Background: Sending QUIT before closing is the polite shutdown — it lets the server finalize the session cleanly rather than seeing an abrupt socket drop. The method is idempotent, so calling it when nothing is connected, or a second time after the session is already closed, still succeeds; that makes it safe to put in cleanup paths without guarding it.
