NetMauMau V0.4

Just released NetMauMau V0.4
I will read that later and try to work it into the ebuid.
Please forgive me, but I'm rather new on Gentoo (but on Linux at all since 1996) and actually I dislike that qmake, but originally the client was only meant as showcase for developers of *real* clients. Else I would have used cmake from the beginning.
