pfSense

Here's some before-and-after config clippings for this. Looks like we may just need to move the <dyndns> entry as-is under <dyndnses> and maybe set interface to wan since that was the only choice on 1.2.x

Before:

<dyndns>
    <type>dyndns</type>
    <username>jim-p</username>
    <password>xxxx</password>
    <host>jim-p.is-a-geek.com</host>
    <mx/>
    <enable/>
</dyndns>

And after:

<dyndnses>
    <dyndns>
        <type>dyndns</type>
        <username>jim-p</username>
        <password>xxxx</password>
        <host>jim-p.is-a-geek.com</host>
        <mx/>
        <enable/>
        <interface>wan</interface>
        <descr>DynDNS for DSL</descr>
    </dyndns>
</dyndnses>

The config upgrade code worked a bit too well, it produced empty dyndns config items on upgrades when none existed before.
