Integrate reverse ENS

[geleeroyale]

When searching for an ETH address, check if there is an ENS name for that address by using reverse ENS and display it in title bar (like it is when searching for an ens name).

Ideas for addresses that have many names:
1 - Display only the first
2 - Display random
3 - Display "... " (collapsible list)
4 - Display for 10 seconds then replace it with the next - loop
