* Displays each local IP adress available (for multi-inferfaces devices)
* Allows a `wget` call on <https://ident.me/> if `dig` is not available (in order to avoid an additional required dependency to `dnsutils`)
* Adds a timeout for public IP requests (to avoid a main script freeze)
* Prefers `decode()` to `re.sub()` calls
* Improves output entries display (?)
* Handles "No Connection" cases (and silences `dig` error on name resolution trouble)
* PEP8 😛
* Adapts (and improves) README with latest stuffs
