Get rid of the logos

[rodber]

I'm getting the impression that the logos are too distracting and that people are focusing on all sort of things instead of actually paying attention to the code.

It is also an exhausting work as for every new package I need to came up with a new idea and the latests logos produced are very boring (writer, etc).

I think that I need to keep these logos to myself, I don't need this distraction on this project.
