Pass additional_records to recursive build_zone calls, closes #229
...
The problem was that custom records defined for a subdomain where implicit
records are otherwise defined (e.g. A/AAAA records for the root) were ignored.
Though additional_records for a subdomain are processed in the base call to
build_zone (the call for the parent domain), and so custom records that don't
override implicits were working fine, those that overrode implicits were
ignored.
This was because the recursive call to build_zone for the subdomain creates the
implicit records (including A/AAAA records for the root), and so by relying on
the base call to add the additional_records fails because has_rec returned
true.
Adding a subdomain's additional_records in the child call works because has_rec
returns false when testing whether to add an e.g. A/AAAA override for the root,
as the defaults have not yet been added.

```https://.../admin/dns/set/desktop.mydomain.com ```

Add IPv6 glue records as well
...
The dns_update script didn't generate IPv6 (AAAA) glue records for the name servers.
This caused http://dnscheck.pingdom.com to complain about a mismatch between the glue records reported by the parent name server and mailinabox nsd.
Here's the failing dnscheck output for reference:
> Checking glue for ns1.my.domain.tld (1.2.3.4).
> Child glue for bgwe.eu found: ns1.my.domain.tld (1.2.3.4)
> Checking glue for ns1.my.domain.tld (1234::1).
> Missing glue at child: ns1.my.domain.tld
> Checking glue for ns2.my.domain.tld (1.2.3.4).

Support dual-stack IPv4/IPv6 mail servers
...
Addresses #3
Added support by adding parallel code wherever `$PUBLIC_IP` was used.
Providing an IPv6 address is completely optional.
Playing around on my IPv6-enabled mail server revealed that — before
this change — mailinabox might try to use an IPv6 address as the value
for `$PUBLIC_IP`, which wouldn't work out well.
