set the SPF record after custom DNS records so that the SPF record doesn't prevent all custom TXT records from coming in

Change read_password() logic to catch short passwords

Currently read_password does not verify password length. But further down the chain, passwords are checked to make sure they are longer than four characters.

If during initial setup, the user enters a password that is shorter than four characters, this will not be caught here, but when the script actually calls management/mailconfig.py to add the user, it will fail without a chance to correct the short password.

The setup script will then continue without an inital user being created and this will confuse users.

status checks: turn missing DNSSEC into a warning instead of an error; omit an error about missing TLSA if DNSSEC isn't in use; if DNSSEC is in use, make a missing TLSA record a warning instead of an error

turn some nameserver status check errors into warnings if the domain resolves correctly since the user might be using External DNS, closes #330

The contacts and calendar apps are now maintained outside of ownCloud core, so we now pull them in from github tags and must enable them explicitly.

fixes #360

drop the list of aliases from the users control panel page because with more than 50 aliases it seems to be so slow it times out

I added OpenDMARC's milter in fba4d470. But this started
setting Authentication-Results headers on outbound mail with failures. Not sure why it
fails at that point, but it shouldn't be set at all. The failure might cause recipients
to junk the mail. See #358.

This commit removes the milter from the SMTP submission (port 587) listener.

run status checks each night and email the administrator with the changes from the previous day's results

If the migration file is missing but the storage directory exists, assume this is a fresh directory -- don't bother trying to migrate, and do write the migration file with the current migration ID.

Update MX records using DNS Update API / Management UI

Give the DNS update tool the ability to customize MX records. Useful if you want a subdomain to send mail to another host.

Changed MX check to respect priorities other than 10.

The status check on MX records now correctly handles domains with
multiple MX records.

Reordered the if a little, added some string parsing, and modified the
OK text to include a warning.

Do not show '_secondary_nameserver' in Custom DNS table

It's redundant and potentially confusing, as any secondary NS shows in "Using a
Secondary Nameserver".

when serving a 'www.' domain, check if the parent domain's ssl certificate can be used besides checking PRIMARY_HOSTNAME

Removing buy_certificate.py which is not working and I don't want to update its call signatures.

all mail domains, not just (top-level) zones, must have an entry in the opendkim key tables so that such outgoing mail gets signed

If you had both x.y.com and y.com configured here, x.y.com mail would not get DKIM-signed.
