* xeth, rpc: implement eth_getNatSpec for tx confirmations * rename silly docserver -> httpclient * eth/backend: httpclient now accessible via eth.Ethereum init-d via config.DocRoot * cmd: introduce separate CLI flag for DocRoot (defaults to homedir) * common/path: delete unused assetpath func, separate HomeDir func
