Yeah, for now anyway.. The problem is that dsync does a two-way sync,
but there's really no good way to do two-way ACL sync. Another problem
is that ACL is a plugin feature, so this should be done by dsync acl
plugin, but dsync doesn't currently support plugins. Both of these could
be fixed some day to support at least the simple conversion case.

If dovecot-acl isn't readable, it was supposed to remove all permissions
from everyone, but I had never tested that code. Fixed now.
