Kongregate game rating bot

#!/usr/bin/env ruby
=begin notice
Hi, what's up ?

This is a prototype to rate all games on Kongregate. Since there are 704 pages with 15 pages on each, and that rating a game brings 1 point, you should easily obtain 10k points, which means a level 25 or so (if admin staff doesn't delete your profile).

NOTE: there is still a bug in the rating values
NOTE2: I didn't use this script on my profile

Dependencies: ruby and the mechanize (0.9.1) gem

Have fun,
