Conformized to current C++ coding standards

Hi Viderizer,

Thanks for your excellent quxbot! I was especially charmed by the interface in main().

I did notice that you do not follow the literature's recommended practices. This is not a problem: C++ is a difficult language and only idiots like me have multiple meters of books about the language. After applying the literature's advice, your code looked very different, yet more conformized, yet still following your architecture.

I'd understand you not accepting this pull request, because for some it takes courage to let go of their work in favor of a 'better' (where 'better' might differ between original and other coder) version. If you desire references to the literature, I can easily generate more than say fifty, backing every one of my actions. If you accept this pull request, I am not only impressed by your solution to the problem, but also by your collaboration.

Thanks for your code, I enjoy it a lot! Cheers, Richel Bilderbeek
