[Bf-python] PyDriver-related problem

[Ken Hughes]

Willian:

Accidentally discovered a problem with the new commit for PyDrivers:

If you run this script from the command line ("blender -P script.py"), 
you get a segfault:

#----------------
import Blender

class Material:
   def __init__(self):
     MATERIALS = self

MATERIALS = None
material = Material()
Blender.Quit()
#----------------

2.41 doesn't have this problem but CVS does.  I traced the problem into 
Blender.Quit(), as far the call to free_blender() in exit_usiblender().
If I move the call to BPY_end_python() back to its previous location 
(after the call to quicktime_exit()) it works fine.

Reading the comment in the source before the new call to 
BPY_end_python(), figured I'd better leave it where it is.
