Some improvements 2

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.

- Moreover I've implemented this feature: https://github.com/eviltik/evilscan/issues/19

- Only the tests related with pause are failing.
