- PyLong_FromSsize_t --> PyLong_FromLong - PyLong_AsSsize_t --> PyLong_AsLong In all places except for those where python api expects PySsize_t (index lookups mainly). - use PyBool_FromLong in a few areas of the BGE. - fix incorrect assumption in the BGE that PySequence_Check() means PySequence_Fast_ functions can be used.
