More Docker Moo

This weekend I finished updating my ToastStunt docker images to fix an issue with some file names and to also add support for PUID and PGID variables so that the containers can be run under a host user.  I'm pretty proud of these containers.  I owe a lot of thanks to the ToastStunt server community and to Lisdude specifically for helping overhaul one of my scripts that was not handling some parameter values with spaces in them properly.  Now it should be a piece of cake for anyone to fire up a ToastStunt moo server in a docker container.  Next I need to go back and add PUID and PGID support to the Lambdamoo server docker images as well.  One step at a time!
