update object_roles

Adding 'DNA', 'Intrinsic' to list.  Intrinsic is my interpretation of

update parser function coreOUTPUT

Adding more scoring, and also a few comments that hint of ways to deduce
currently unsolved kills.  I'll work on that once this current round of
scoring additions is finished.
