* Support installing extra packages in Docker images at runtime. This enables users to pull in additional packages more easily if they need to. It also allows us to drop optional runtime dependencies from our base images without making life significantly more difficult for users who actually need them. * Reorganize code and fix issues brought up in review. * Make new variable empty by default instead.
