docker-compose failure

Docker compose sometimes spits back this message:

When that happens, you must remove data_rabbit and data_mongo directories.

We should update the readme..

I fixed the docker-compose.yml not to use a local directory for data volumes (not sure what I was thinking the first time). Should be much smoother now.
