Subject: Registrar and contractInfo handling * 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
