- Another bug in get_sort_family_of (sort-polymorphism of constants and

  inductive types was not taken into account).
- Virtually extended tauto to 
  - support arbitrary-length disjunctions and conjunctions,
  - support arbitrary complex forms of disjunctions and
    conjunctions when in the contravariant of an implicative hypothesis,
  - stick with the purely propositional fragment and not apply reflexivity.
  This is virtual in the sense that it is not activated since it breaks 
  compatibility with the existing tauto.
- Modified the notion of conjunction and unit type used in hipattern in a 
  way that is closer to the intuitive meaning (forbid dependencies 
  between parameters in conjunction; forbid indices in unit types).
- Investigated how far "iff" could be turned into a direct inductive
  definition; modified tauto.ml4 so that it works with the current and
  the alternative definition.
- Fixed a bug in the error message from lookup_eliminator.
- Other minor changes.
