Fix throwing things off rope, also make throwing things a bit more generic and gear density dependent (so you can throw mines further, and also throw dynamite a little).
#include <QApplication>
#include "mainform.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyWindow *mainWin = new MyWindow;
mainWin->show();
return app.exec();
}
