BPython:

-- removed struct Script (DNA_script_types.h) from makesdna to blender/include/BPI_script.h
   (BPI meaning Blender Python-related external Include file).
   Had agreed with Ton that makesdna was not the proper place for it.
-- fixed two small warnings in Ipo.c (variables might be used uninitialized)
-- fixed a bug reported on blender.org's python forum by Wim Van Hoydonck (aka tuinbels):
   Blender would hang if a script failed.  My fault, accidentally put a node=node->next type call outside the while loop check, so it never ended.

With makesdna/DNA_script_types.h removed and include/BPI_script.h added, msvc projectfiles will need to be updated.  Sorry to do it now, but I promissed I'd fix this before next release.
