Chai returns bool instead of int

    \return Return 0 if no error occurred.

Also CChaiHaptics.cpp has an incorrect return var.

// 2. Open a connection to the haptic device.
        bool hflag = tmp_haptic_device->open();
        if (false == hflag)
        {
          std::stringstream ss; ss<<"Could not connect to haptic device: "<<i;
          throw(std::runtime_error(ss.str()));
        }
        else
        { std::cout << "\nConnected to haptic device: "<< i << std::flush; }
