NetworkManager: add dnsmasq.d/mikaela.conf

Browse Source 
I want DNSMasq to behave a little differently from the NetworkManager
defaults.

The default cache size of 150/400 seems a little small and 10 000 probably
won't be full soon and I am sure modern systems at least at home where I
am using dnsmasq again won't suffer from it.

By default dnsmasq started by NEtworkManager only listens on 127.0.0.1
while ::1 also exists, I want it to be also listened on in case anything
decides to try querying with it.

DNSSEC is not checked by default while I want that behaviour, but as I
am using OpenDNS I cannot make it verify unsigned zones are unsigned :(

Also add symlink to trust-anchors.conf that should ship with DNSSEC to
avoid having to deal with it manually. It should work as a reminder that
it's also needed.
