Fails to write files to mounted src code volume

[alexdelifer]

Since the container is running as app it doesn't have permissions to write .dump files to the code volume.

This means new features like --addon and --dump do not work properly until this is fixed.

This would fix #41 and would allow for
addon: misra.py
to work

seems like the codeclimate cli tool forces the user to be 9000:9000
I wrote a entrypoint.sh that creates a app user and appgroup group, chmods and chowns, all for it to be blocked by some hardcoded args.

I also don't think it's possible for the codeclimate containers to output to the /code volume since it's mounted :ro during execution.

too bad, will investigate another time.
