BGE performance:

- Vast performance increase when removing scene containing large number of 
  objects: the sensor/controller map was updated for each deleted object, 
  causing massive slow down when the number of objects was large (O(n^2)).
- Use reference when scanning the sensor map => avoid useless copy.
- Remove dynamically the object bounding box from the DBVT when the object
  is invisible => faster culling.
