frontlib refactoring socket.h now completely wraps all the lowlevel neworking, so it would be easy to switch away from SDL_net if needed. Also reduced global state by making an IPC connection an object-like thing.

#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}
