logfile
- add logfile option to ethereum client flags
- fallback to StdOut
- Logger appended to ethutil.Config.Log loggers
- wrapper uses ethutil.Config.Log
non-interactive option
- add -y flag for non-interactive use
- refactor main
- output to logfile (not ideal..) but not to all ethutil loggers for privacy
