Added a warning for people that try to run a non-headless browser in a docker container. It errors in a very unhelpful way, and so this code tells the user in the output what's happening and also forces headless = True. If a user actually means to run a non-headless browser and view via X11 or something then the warning/output will lead them to the right place that they need to tweak.
