Hi,

I made a little change to have [docker] (https://www.docker.com/) and/or supervisord support with msm.

Processus started by Docker must not return otherwise the container is stopped.

I added a "start nodetach" command to msm to prevent msm from detaching.
Then, msm will wait until a INT signal is received to properly close minecraft by calling command_stop.

Best Regards,
