Fix set:

Browse Source 
1) Create validation structure even if not proposing (but if validating)
2) Fix hashes in status change messages, do it only one way
3) Don't spin right at wobble time.
4) Report accept status change on new last-closed ledger, not new open ledger.
5) Make sure validation count is correct even if we first encounter a ledger on ourselves (not a peer)
6) At end of consensus, assume nodes cycled (until they report otherwise). By doing nothing,
we effectively assumed they didn't.
7) Miscellaneous cleanups and fixes.
