[MaraDNS list] Config file parser bug

Hi,

just another config parser bug in 1.4.03-1.1 (as it comes with Debian
Squeeze) that I ran into today: if a list is supposed to be comma
separated, forgetting the comma causes the rest to be silently ignored.
This was what broke my config:
| ipv4_bind_addresses = "127.0.0.1 188.40.77.81, 172.16.42.129"
The result was the NS only listening on localhost.

Haven't looked at the source yet but maybe someone who is familiar with
it already will find it easy to fix.

cheers,
	Matthias
