IMAP/SORT support in Archiveopteryx

The SORT extension enables the client to sort messages without downloading them. There are exactly seven sort criteria, which may be combined arbitrarily.

It should be noted that the address-related sorting provided by SORT uses only the localpart: and are considered the same address by SORT. SORT=DISPLAYFROM improves on this.

SORT is used by some webmail clients, not many normal IMAP clients.
