As a first step towards #1112

Add a call type to the srml-grandpa module where peers can provide two votes that are equivocating. This will check that both are of the same type, signed by the same validator , and are not equivalent.

If so, it will not currently do anything. After #1699 we can slash for it.

the prevote_equivocation and precommit_equivocation functions on Environment should trigger this transaction to be sent.
