Merge pull request #170 from StochSS/master

Gotta propagate the anyjson fixes down
add support in infrastructure manager for amqp broker (to replace sqs)
add key_prefix in relevant methods to allow for specifying machines by a common prefix, enforce use of amqp broker in backend and ensure that the broker is always running, add new mcem2 job type, check for cores parameter and launch one micro instance/worker per core requested and subscribe them all to the same queue, implement master task and slave task as wrappers around the master and slave routines within mcem2, the master also has an update process that updates output bucket in s3 every 30 seconds
update front end handlers slightly to accept new result type of executeTask method and to use the user_id for the key_prefix parameter where appropriate
