Kurt 6182f889a6 Add learnset moves similar to games
Instead of looping, if the moveset is full and a new move is added, the game shifts all arr[1..] down one slot then adds the move at the end.
Since we don't need to keep track of PP/PP Ups, we can just defer the shifting and do n % 4 rotations at the end instead of n rotations (one on each move added).
