rename MinFrameTime as FrameTime, since it is not a minimum but a target value; retune its value a bit so reported FPS is closer to integer value; change ode step size acording to reduce jitter in phys FPS; Make Statistics Scaling factor (fludge factor) configurable. (legacy default of 5.0 in code)
