Added MRS, MRL from ZF/ROOT.ML. These support forward proof, resolving a rule's premises against a list of other proofs.

This commit should not have been necessary. For some reason, the previous commit did not update genrec.ML. There were still occurrences of SIMP_TAC. Was the commit perhaps interrupted??

make-all now has set +e so that New Jersey runs will continue even if some logic fails. change_simp added to help change to new simplifier.

Installation of new simplfier. Previously appeared to set up the old simplifier to rewrite with the partial ordering [=, something not possible with the new simplifier. But such rewriting appears not to have actually been used, and there were few complications. In terms.ML setloop was used to avoid infinite rewriting with the letrec rule. Congruence rules were deleted, and an occasional SIMP_TAC had to become asm_simp_tac.

lcp [Fri, 17 Sep 1993 16:52:10 +0200] rev 7
Installation of new simplifier for ZF/ex. The hom_ss example in misc.ML is particularly delicate. There is a variable renaming problem in ramsey.ML/pigeon2_lemma. In some cases, rewriting by typechecking rules had to be replaced by setsolver type_auto_tac... because only the solver can instantiate variables.

lcp [Fri, 17 Sep 1993 16:16:38 +0200] rev 6
Installation of new simplifier for ZF. Deleted all congruence rules not involving local assumptions. NB the congruence rules for Sigma and Pi (dependent type constructions) cause difficulties and are not used by default.
