EthStore was only being used for tracking account balances and nonces now, so I removed its block-tracking duties, renamed it account-tracker, and removed it as a dependency from `KeyringController`, so that KRC can go live on without a hard dep on it.
These external modules now have their own test coverage and build enforcement. This allowed me to somewhat more easily add good tests around our personalSign strategy (held now in [eth-sig-util](https://github.com/flyswatter/eth-sig-util), and allow each of the keyrings to import that, etc.
