Makes ServerSocket multi-platform, mainly by working around some small API differences. The code is largely the same, there should be no differences on Linux. Also moves WSAStartup() and WSACleanup() up to the Socket level as static methods because it's used by both ClientSocket and ServerSocket, and because it doesn't make sense to do that in the socket class as that would prevent one from using several sockets.
