DynDNS support for ddns project.

Hello guys,

i've created a patch for the Dynamic DNS client for IPFire. (http://git.ipfire.org/?p=oddments/ddns.git;a=summary)

My patch will add support for the very popular "dyndns.org" provider. However I wasn't able to test my changes, because I don't have any account there and I seems new members have to purchase to use use it.

So, I need your help to test my changes and finally be able to support that provider in the next major version of IPFire.

Best regards,

Stefan
