* ethcore: don't validate difficulty when ignoring seal check
* ethcore: fix block verification test
* ethcore: document skipped verifications when check_seal is disabled
This adds block reward contract config to ethash. A new config `blockRewardContractCode` is also added to both Aura and ethash. When specified, it will execute the code directly and overrides any `blockRewardContractAddress` config. Having this `blockRewardContractCode` config allows chains to deploy hard fork by simply replacing the current config value, without the need from us to support any `multi` block reward scheme.

This is necessary to make the number of seal fields dynamic,
e.g. activating a transition on a certain block number that changes
the seal.
* aura: add transition to enable empty step messages

* aura: report skipped primaries when empty steps are not enabled
* aura: fix tests

* aura: add tests for rolling finality with multiple signatures
* engine: fix validator set test
In this test the block validation wasn't failing because the block was in the
future (expected failure) but was instead failing because the author of the
block isn't the expected authority. Since we added reporting of blocks produced
by the wrong authority this test started failing.
