Provide an FTP ACCT Account Identifier

Demonstrates the Account property, which supplies the value for the FTP ACCT command sent after USER/PASS when a server requests it.

Background: ACCT is a vestige of early FTP, where an account identifier could be required in addition to the username and password — think mainframe billing codes or storage-group selection. It is very rarely needed today; almost every modern server authenticates with USER and PASS alone. Set this only when connecting to a legacy host that explicitly asks for account information after login.
