Bugfixes for frame number boost:

- Found several places, where people explicitly casted the frame number
  to short.
- Fixed the crash in BPY_interface by adding an empty line (to make it
  recompile everywhere, make clean doesn't help...)

  For the build system maintainers:

  Problem was: The change in makesdna changed the position of the
  scriptlink structure. BPY_interface.c somehow didn't get recompiled
  (not even after a make clean!!!) which triggered crashes on adding
  scriptlinks.
