[#872] Output contract events in binaries

Side note: the issue description says morley emulate transfer doesn't output events. It does (as it does any operations), but the output could be improved, so I did that.

Description

Problem: morley-client binary doesn't output contract events on transfer.

Solution: make it.

---

Problem: Buildable instances for Morley.Michelson.Typed.Value.Operaition' do not output values attached to operations due to instr parameter not being specified.

Solution: Require quantified Buildable constraint for forall t. Value' instr t on the buildable instance, output values in addition to everything else.
