fix up dev.cfg so that nobody will ever have to edit it, by letting the
important params be overridable in loggerhead.conf.

make start-loggerhead actually daemonize, write a pid file, and write logs
to normal log files, instead of requiring 'nohup' stuff.  ie act like a real
server.  added stop-loggerhead to do a clean shutdown.  changed the README
to clarify how it should work now.
