Work around there being a void floor in Bedrock (#1405)

Browse source 
* Work around there being a void floor in Bedrock

If the player's Y coordinate is -38 or below, we teleport the player below the void floor and they can safely die. :)

* Don't teleport if below Y -40

* sigh

* Have floorY be its own variable

* Add more comment

* More comments

* Finish my thought
