Dovecot 1.1.14 upgrade requires user intervention

Due to a limitation in pacman's conflict checking when a directory is replaced by a file with the same name, the upgrade to dovecot-1.1.14-1 requires manual interaction. It's safe to update using "pacman -Sf dovecot" to avoid two file conflicts. Please also have a look at the changed file layout and changes in /etc/dovecot/dovecot-example.conf.
