Updated imapfilter to 1.2.2.

Patch from PR 34130, which includes resetting the MAINTAINER to the
default value.

Version 1.2.2 - 1 August 2006
-----------------------------
- Bug fix; a mix up of connections could happen in certain circumstances, when
  a hostname and/or username was a prefix of another hostname and/or username
  respectively, or when the same hostname and username was used to connect to
  a different port.
- Bug fix; the list()/lsub() functions parsed mailboxes/folders whose names
  contained spaces incorrectly.
- The list() function now does not return the folder itself, when listing
  mailboxes inside a specific folder.
- It is now possible to define new user keywords for messages inside a mailbox,
  apart from the standard system flags.
