Small bugfixes an new compatibility with FreeBSD10

- Changed default IP check site to ifconfig.me
- Added a switch to use _drill_ instead of _nslookup_ because FreeBSD
10 switched from _bind_ to _unbound_
- Renamed _$HOSTNAME_ to _$DOMAIN_ to work around potential conflicts
with _$HOSTNAME_ that's set by the host itself
