NetworkManager-dns-dnsmasq-1.0-bp160.1.7

- Require dnsmasq and sysconfig: the script explicitly targets
  integration between NetworkManager and dnsmasq, so it makes sense
  to require both components. Additionally, sysconfig is used to
  detect if the configuration is done properly for this
  (boo#1236047).

- Initial: NetworkManager dispatcher script for DNS dnsmasq configuration.
