Change from ActiveMQ topics to queues

[MarcusNoble]

Need to change to using queues so that multiple autoreduction servers could listen for jobs without both actioning it.

Only requires changes in settings.py and queue_processor.py

For Tester:

1. Connect to datareducedev.isis.cclrc.ac.uk
2. sudo su
3. export PATH="/usr/local/bin:$PATH"
4. python /var/www/autoreduce_webapp/manage.py test autoreduce_webapp.tests.QueueProcessorTestCase

I get the message:
