By scanning the local IP-space of connected/configured internal (non-gateway) interfaces, discovered IPs should be auto-added to the definitions list using their hostname as the title (if available) otherwise just fill in the IP for both the address and the name.

This saves admins having to define their objects from scratch, and they can always delete the object definitions they don't want/plan to use. This should be done either automatically, as part of the wizard, or on request.
