BGE : addObject in python without reference object.

Browse Source 
Making the reference argument optional for the addObject function.
```
scene.addObject("Cube")
```

This allows to keep the rotation, scale and position of the original object.
To avoid layer problems with lights if the reference arguments is None, the new object have the same layer than the active layers in scene.
