Some improvements

Hi, I need these features to add Evilscan to the new version of Bluebox-ng (a VoIP security tool), so I've made these changes:
- I wasn't able to install GeoIP module, moreover it has some known problems and it's not fully implemented in JavaScript. So I changed it for "geoip-lite" module which is what I use, IMHO, a better choice today.
- I've also added the example of the README to the source code.
