New brand identity for Cuberite.

@bearbin I suspect that attribution in a license file accompanying the app would be more than enough. As for the WTFPL, no one really knows if it would stand up in court, so if you were going to have an open license, its probably better to go for CC0.

The logo is also used on all websites, documentation and will also be used in other places where attribution is infeasible.

I agree with your suggestion about licensing of logos - for a logo to be accepted the creator should license it CC0. WTFPL is identical to public domain, except less explicit, so it shares any problems there may be with public domain licensing.
