25 * CommandHandler for the RNTO command. Handler logic:
26 * <ol>
27 *  <li>If the user has not logged in, then reply with 530</li>
28 *  <li>If this command was not preceded by a valid RNFR command, then reply with 503</li>
29 *  <li>If the required TO pathname parameter is missing, then reply with 501</li>
30 *  <li>If the TO pathname parameter does not specify a valid filename, then reply with 553</li>
31 *  <li>If the TO pathname parameter specifies an existing directory, then reply with 553</li>
32 *  <li>If the rename operation fails, then reply with 553</li>
33 *  <li>Otherwise, reply with 250 and remove the FROM path stored in the session by the RNFR command</li>
34 * </ol>
35 * The supplied pathname may be absolute or relative to the current directory.
