core, miner: miner header validation, transaction & receipt writing
* Miners do now verify their own header, not their state. * Changed old putTx and putReceipts to be exported * Moved writing of transactions and receipts out of the block processer in to the chain manager. Closes #1386 * Miner post ChainHeadEvent & ChainEvent. Closes #1388
