[20161003] Very Basic JPos Control of Valkyrie in srSimulator

What you can see in the video is low stiff joint position control for both virtual joints and actuated joints. That's why we can see the valkyrie moves like it is in the air (or space).

In terms of compile, motion control library is connected with srSimulator (in the R5_SRC_Simulator/srSimulator folder) but the same balance control code is not working in srLib. I believe there is small bug in the simulator. We will fix it soon. 

As the debugging process, I fix the body in the air but not in the fixed link way but in the feedback control way.
