* resolver -> common/registrar * global registrar name registry interface * add Call to resolver backend interface * the hashReg and UrlHing contracts now initialised from global registry * initialization of contracts uniform * improve errors and more econsistent method names * common/registrar/ethreg: versioned registrar * integrate new naming and registrar in natspec * js console api: setGlobalRegistrar, setHashReg, setUrlHint * js test TestContract uses mining - tests fixed all pass * eth/backend: allow PoW test mode (small ethash DAG) * console jsre refers to resolver.abi/addr, * cmd/geth/contracts.go moved to common/registrar
