chore(library/init/meta/simp_tactic): fix typo

feat(library/init/meta/interactive): unfold is now based on the simp framework
...
See issue #1694 .
There is an orthogonal issue. `simp` (and consequently `unfold`) cannot be used to
reduce projections (e.g., `has_add.add`). This issue has been
previously raised by @Armael, but it was not addressed yet.

closes #1675
After this commit, the following example works as expected.
```
example (p : nat → Prop) (a b : nat) : a = 0 ∧ b = 0 → p (a + b) → p 0 :=
begin
intros h₁ h₂,
simp [h₁] at *,
/- produces the state
(p : nat → Prop) (a b : nat)
h₁ : true
h₂ : p 0
|- p 0
-/
assumption
end
```
as expected.
Remark: the original issue raised by issue #1675 is actually solved by the
`simp_all` tactic.

feat(library/init/meta/simp_tactic): improved simp_all tactic

It now performs self simplification, and the performance is slightly
better. As described at issue #1675 , only non dependent propositions
are considered.

`rewrite` tactic improvements

- 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.
