Added a message queue

Added kombu, an interface to AMQP

Added react.py, sample reaction script with a kombu consumer.
Should be run separately. Just loops forever listening for
messages on the PASS_EVENTS queue/

Added queues.py, define an exchange and two queues to use
for the message queue

Replaced runthis.sh with audit.py, changed runthis.json to
audit.json. audit.py has send_message(), which sends a message
to the PASS_EVENTS queue

Configuration data for audit.py and react.py should be picked up
from audit.json and react.json.

Added H304, H302 to pep8 ignores
