Hostname resolution: improve host identification in UI when hostname is same for more than one IP address

The web UI allows me to set the same hostname for both the wired and wireless interface on my laptop using DHCP address reservation. However, elsewhere in the UI, the first interface shows up as the hostname, and the other as the IP address. My proposed enhancement would be to, where more than one IP address has the same hostname assigned, identify the host in the UI as 'hostname (IP address)'. An alternative would be to require hostnames to be unique - which I would rather you didn't do :wink:

Implemented.
