Example setup is out of date for recent RabbitMQ versions

[prb]

With RabbitMQ 1.5.4, some of the commands (permissioning) in the `examples/rabbitconf.rb` fail. These failures don’t affect the functioning of the examples, but they don’t exactly inspire user confidence, either…

There are also some places in the examples where hardcoded paths are still in place, e.g., `examples/crew.rb`.

Ran into the same thing here.

Version 1.6.x
sudo rabbitmqctl set_permissions -p /nanite mapper '.' '.' '.'
sudo rabbitmqctl set_permissions -p /nanite nanite '.' '.' '.'

Yeah this is unfortunate that rabbit has changed between versions. The scripts right now will run both of these settings which will look like it failed for some commands but will in the end leave you with a working rabbitmq server setup as it will run the proper command for whichever version of rabbit you have.

I'm going to close this ticket with a caveat that you can safely ignore the errors and still end up with a working system.
