`rewrite` tactic improvements - Add support for `auto_param` and `opt_param` - Order new goals using the same strategies available for `apply` - Allow user to set configuration object in interactive mode. @Armael This commit should address the issue you raised about the order of new goals in the `rewrite` tactic. See new test tests/lean/run/rw1.lean for examples.
