* CommandHandler for the RNTO command. Handler logic:

* <li>If the user has not logged in, then reply with 530</li>
* <li>If this command was not preceded by a valid RNFR command, then reply with 503</li>
* <li>If the required TO pathname parameter is missing, then reply with 501</li>
* <li>If the TO pathname parameter does not specify a valid filename, then reply with 553</li>
* <li>If the TO pathname parameter specifies an existing directory, then reply with 553</li>
* <li>If the current user does not have write access to the parent directory, then reply with 553</li>
* <li>Otherwise, rename the file, remove the FROM path stored in the session by the RNFR command, and reply with 250</li>
* </ol>
* The supplied pathname may be absolute or relative to the current directory.
