Added default autostart file (and removed the old one) which also informs about what is going on (that you maybe want to have your own autostart)
We actually don't want to start the whole celluloid system until we really know everything is good to go. This is esp. the case when only help or version is reported due to command line arguments

Lines like

D, [2013-11-27T17:35:42.155304 #75589] DEBUG -- : Terminating 4 actors...

will not appear anymore when reporting version number or help
slightly better logging
removing remnants of old setup. this is now the responsibility of the the agents.
Major linting - also using fail instead of raise now whereever suitable (nearly everywhere).

See http://avdi.org/talks/exceptional-ruby-2011-02-04/ for a better understanding why.
