feat(*): distinguish between logical and runtime exceptions.
...
Now, we use throwable as the new base class for all Lean exceptions, and
exception is the subclass for "logical" exceptions.

fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286
...
The problem was that heq type is
Pi {A : Type} (a : A) {B : Type} (b : B), Prop
The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.
The fix is to remove this assumption.
