Subject: 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
