* Queries against the store must be prefixed with the path "/store"
* RecentValidator store now take pubkey instead of address, is sorted like Tendermint by pk's address
* RecentValidator store now take pubkey instead of address, is sorted like Tendermint by pk's address
* `gaiacli query candidate` takes and argument instead of using the `--address-candidate` flag
