When I first opened #161 I made small changes that would help me autocreate a world if it didn't exist. Then as time went on I forgot about the PR and made further changes that were never supposed to be included, but were merged anyways. This PR sets most of those changes back so that the Dockerfile doesn't break while maintaining the good changes included (fixing plugin copying and supporting the autocreate flag).
