Main/NetworkAdapter+Machine+Appliance+SystemProperties+Medium+Console+Settings+IDL: make NAT networking a separate network attachment type which improves the user experience, store the necessary settings, plus changing the design of the methods which will move images and entire VMs, they lacked a progress object
Frontends/VirtualBox: adapted fully, can configure NAT networks with proper drop down list support
Frontends/VBoxManage: also supports NAT networks completely, and adds the long missing code to list intnets
