The server currently starts without error messages (on OS X) if you also
install redis and rabbitmq-server and start their processes without any
further configuration:
$ redis-server
$ rabbitmq-server
$ sensu-server
Haven't tried much more yet, but will in a bit.
(Amended: fix whitespace and string literal formatting issues, and
superfluous dependencies created by the generator script.
Thanks the-kenny!)
