* Add redmew_surface * Change map_layout to have all maps use redmew_surface * Maps: switch hardcoded nauvis refs to redmew_surface * Features: switch hardcoded nauvis refs to redmew_surface * Per discussion, removal of RSO * Changes to files based on linting warnings/errors * ent_functions: remove functions from global scope, ignore remaining linting warnings (~100 remaining) * borg_planet: ignore linting warnings (88 remaining) * mazes refactored * Changed global.lua so events are run in the order they are registered
