core/evm, core/vm: improved evm trace output
* Improved the standard evm tracer output and renamed it to WriteTrace which now takes an io.Writer to write the logs to. * Added WriteLogs which writes logs to the given writer in a readable format. * evm utility now also prints logs generated during the execution.
