Changed battle_config definition to extern to avoid mistakes in plugins

- This avoids plugins incorrectly using battle_config (with unreliable
  results) instead of using the proper interface, battle->bc.
- Edited various #defines to use battle->bc instead of battle_config so
  that they can work perperly in plugins as well.
