Big tabula rasa.

I decided to continue this project in C, rather than C++. This is
mainly because I have been using C quite often lately, and started to
love the simplicity of the language.

Furthermore, I have never actually really programmed *real* C++, so
there are too many things I don't understand. This is why I moved away
from the idea of using C++.

Here I kept the essential parts (networking), and removed the rest.
