Changed
Field address of eth_getLogs, eth_newFilter methods accept both single address or addresses array.
eth_getLogs, eth_newFilter methods could be called with null or without arguments. 
Method get_block with 0 in argument return genesis block.
Method eth_chainId in ethrpc return uint_t instead of hash_t.
Fixed
