End Cutscene/Biome Unlocking

a cutsene when traveling through the end portal triggers a first-person view of the player looking around during and after the "inside of the end portal" scene. Additionally, there should be a "/skip_cutscene" command too! Also, biome/dimension unlocking would be cool, even if only some animated words pop up on screen when you first enter a biome/dimension. Thanks so much for listening!
