Exppython:

- Fixed a problem with control of the global Python dictionary persistence:
    Blender.ReleaseGlobalDict(bool) should now work fine.
- Trying to fix the sigsegv crashes on Windows:
    They happen when we try to "print" our objects, like Lamps or Cameras.
    Following advice from the Python Embedding doc, removed the tp_print
    method from Camera and also improved its tp_repr one, that will be used
    as print, repr() and str() for Cameras.  If this test works all other objs
    will be updated accordingly.
