Clone_weapon now returns an ID

[FatherOfEgg]

clone_weapon

• Now returns an i32, which is the cloned article's ID
  • FIGHTER_X_GENERATE_ARTICLE_A = 0x2 + clone_weapon(...);
0x2 is the number of articles your fighter originally has.
• Panics when trying to clone a new weapon, and that agent already exists
  • Doing clone_weapon(mario, x, captain, apple) and clone_weapon(link, y, captain, apple) panics
  • But if someone did this for some reason, with the dev plugin, it wouldn't panic, and returns the ID for link_y(captain_banana):
    clone_weapon(mario, x, captain, apple)
clone_weapon(link, y, captain, banana), and then later changed it to clone_weapon(link, y, captain, apple)
