First commit for #139 - Comparison Testing for REST API

The code works and brings correct results.
There is a lot of duplication now, refactoring is already in progress.
The classes should also be moved to another package/module.

The input file for comparison should have the following format:
whois/ripe/mntner/RIPE-DBM-STARTUP-MNT
whois/test/mntner/owner-mnt
whois/search?query-string=AS102&source=RIPE
whois/search?query-string=AS102&source=TEST
...
refactoring on rest/query comparison files for #139

(previous commit: 9f16771)
added rest comparison to maven comparison profile (issue #139)
