Bunch of work to get the portals working - entering the portal as a player or as a vehicle will instantly teleport the the opposite side - portals are spawned at runtime and sized to the size of the island - portals can be spawned at any of the 4 cardinal directions of the island - for testing leave the island from the north side and enter the deep sea on the south - will be spawned 200m from the edge of the deep sea (in the center of the ocean for testing) - teleport the player the frame after they enter since making the player sleep deletes the rigidbody immediately and unity doesn't like deleting physics objects inside the callback they enter the trigger (later this will be hidden by effects) - refactor the name of some code to make it nicer - portals will show as big green boxes to make testing easier, can be toggled with `deepsea_portals_visible` convar - fix PointEntity<T> not intializating the singleton instances as soon as possible
