Prefix generic function names, normalize style in featured-image-generator

- Rename generate_bisected_image, handle_image_request, serve_image,
  save_image_to_cache, add_image_generator_endpoint to tony_sportspress_*
  to avoid global namespace collisions
- Guard $team1/$team2 against null before accessing ->post_modified
- Unify the two logo-placement loops into a single foreach
- Normalize indentation to tabs throughout
- Fix missing space before => in sp-event-export normalize_request_args
