- Extension de "generalize" en "generalize c as id at occs".

- Ajout clause "in" à "remember" (et passage du code en ML).
- Ajout clause "in" à "induction"/"destruct" qui, en ce cas, ajoute
  aussi une égalité pour se souvenir du terme sur lequel l'induction
  ou l'analyse de cas s'applique.
- Ajout "pose t as id" en standard (Matthieu: j'ai enlevé celui de
  Programs qui avait la sémantique de "pose proof" tandis que le nouveau
  a la même sémantique que "pose (id:=t)").
- Un peu de réorganisation, uniformisation de noms dans Arith, et
  ajout EqNat dans Arith.
- Documentation tactiques et notations de tactiques.
