* WIP * Convert Ethcore error to use error_chain * Use error_chain for ImportError and BlockImportError * Fix error pattern matches for error_chain in miner * Implement explicit From for AccountsError * Fix pattern matches for ErrorKinds * Handle ethcore error_chain in light client * Explicitly define Result type to avoid shadowing * Fix remaining Error pattern matches * Fix tab space formatting * Helps if the tests compile * Fix error chain matching after merge
