* Added some comments next to portions of the code which are obsoleted by the final form of RFC 5464 (IMAP METADATA extension). The dependency on LIST-EXTENDED has been removed, and the Bynari Connector never needed it in the first place. After the code freeze is over we will remove the portions of our unfinished LIST-EXTENDED implementation which were to provide metadata, *or* we may simply remove the unfinished LIST-EXTENDED implementation altogether.
