Show contacts with full database support

This example is nearly the same as example #1. Now we try to load the provided databases and now (if successfully loaded) all contacted aircrafts can be written will full type informations, flight informations and airport informations (if the flight was found in the flight database). The databases will be loaded from the same directory where the binary will started except you change the path.
