Revision: 8968
Log message:

      - Rewrote the forward-chainer:
        - to be more efficient (less idT calls, etc)
        - to more aggressively prohibit "no progress" steps
        - to thin out dups during forward chaining (where we already know that they
          are dups)
      
        This sped up status-all by almost a third!
      
      - Fixed the broken proofs in itt_hoas_sequent_term_wf.
