Small Changes :3

[Serial-V]

• Small entity filtering to check if the entity identifier exists in the world's entity palette, if not well skips it.
  • This just to avoid runtime crashes
  • This can be better but simple for now
• Added Facing param for the /summon command, allows operators to summon a entity and makes the entity face towards the player.
  • This could be improved in the future?
