*Ray counters (number of BB/primitive tests/hits and other raytrace counters) can now be enabled/disabled at compile-time.

#define RE_RAYCOUNTER (/source/blender/render/extern/include/RE_raytrace.h)

*Some other small organization on code

(will be disable as this only matters for testing and developping)
