[Dovecot] v1.1.1 released

http://dovecot.org/releases/1.1/dovecot-1.1.1.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.1.tar.gz.sig

Hopefully this release lives a bit longer than v1.1.0.

- Maildir: When migrating from v1.0 with old format dovecot-uidlist
  files, Dovecot may have appended lines to it using the new format and
  later broken with "UID larger than next_uid" error.
