Merge #4566 #4657

4566: Change PublicKey on Bid r=EdHastingsCasperAssociation a=wojcik91

Implements casper-network/ceps#91

4657: Prevent stray `accounts.toml` files from breaking upgrades r=EdHastingsCasperAssociation a=fizyk20

The rewards calculation used to take the validators from `accounts.toml` when writing zero rewards to validators at genesis or at an upgrade point. This is now just replaced with an empty map, which has the same effect and doesn't depend on external data.
