Present the option to use syslog

Expanding #4

Extend with syslog functionality, maybe as a string syslog:file:host:port passed to logfile (option and conf-file)

As a sidenote, should supervisord be the recommended way to deploy? This would make life easier as it will take over log rotation etc. greenbalance logs to stdout/err as per default already.

Maybe have a look at http://packages.python.org/Logbook/
