- 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.
