solidity compiler and contract metadocs integration
* common/compiler: solidity compiler + tests * rpc: eth_compilers, eth_compileSolidity + tests * fix natspec test using keystore API, notice exp dynamically changes addr, cleanup * resolver implements registrars and needs to create reg contract (temp) * xeth: solidity compiler. expose getter Solc() and paths setter SetSolc(solcPath) * ethereumApi: implement compiler related RPC calls using XEth - json struct tests * admin: make use of XEth.SetSolc to allow runtime setting of compiler paths * cli: command line flags solc to set custom solc bin path * js admin api with new features debug and contractInfo modules * wiki is the doc https://github.com/ethereum/go-ethereum/wiki/Contracts-and-Transactions
