More fixes/improvements
...
* Log the right shard number for wallet/getFreeToken
* Don't try to use empty commit bitmap from genesis block
* Fail hard if block reward or finalization fails
* Log the public key if message sig verification fails
* Extract and save chain state from received blocks in order to
eliminate deep tail recursion
* Properly deep copy chain config (previously ChainID was being shared
among chains)
* Eliminate chain use-before-init window in node.New()
* Save genesis epoch shard state in new blockchain database
* Do not check epoch of the received shard state message (temp
workaround – we should introduce the check elsewhere)
* Propose an empty block if no transactions have been received for 10
seconds
