Proposed patch to correct /etc/resolv.conf ordering.

Description of problem:
In currently version of NetworkManager in Fedora, IPv6 DNS nameservers are getting prioritised last in /etc/resolv.conf this doesn't seem right compared to prioritization of IPv6/IPv4 in general IP stacks (for instance, web browsing).

Version-Release number of selected component (if applicable):
NetworkManager-0.8.1-10.git20100831.fc14.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Set up a dual stack IPv6/IPv4 network, in my case radvd is announcing IPv6 nameservers & IPs, dhcp is announcing IPv4 IPs & nameservers.
2.
3.

Actual results:

NetworkManager will write a /etc/resolv.conf in the following order:

domain <foo>
search <bar>
nameserver [IPv4 VPN Nameservers]
nameserver [IPv4 LAN Nameservers]
nameserver [IPv6 VPN Nameservers]
nameserver [IPv6 LAN Nameservers]

This means that DNS queries will happen over the IPv6 stack last.

Expected results:

My expected ordering is:

* IPv6 VPN Nameservers
* IPv4 VPN Nameservers
* IPv6 LAN Nameservers
* IPv4 LAN Nameservers

I prioritise IPv4 VPN over IPv6 LAN in consideration that there will be some IPv4 only VPN networks around for a while.

Additional info:

I have a patch that has worked over the last week on my home/personal laptop that corrects this issue. (Attached)
