Bug#772162: debian-edu-install: preseed dovecot-core to enable ssl certificate creation.

[Wolfgang Schweer <wschweer@arcor.de>]

Package: debian-edu-install
Version: 1.718
Severity: important
Tags: patch pending

As of dovecot-core version 1:2.2.13-8 SSL certificates are no longer 
created by default. A preseed entry should be added to enable it.

The fix has been committed to git.

Please note: While testing the fix I noticed that dovecot-core postinst 
doesn't seem to respect
'dovecot-core dovecot-core/create-ssl-cert boolean true'
(default is 'dovecot-core dovecot-core/create-ssl-cert boolean false').
Actually, the ssl creation code seems to be missing in postinst.
I'll file a bug against dovecot-core.
