Cleaned up obsolete code in PocketProvider and fixed the assignment of hasNoSky so that it actually applies. Also overloaded getActualHeight() so that we return 256 despite hasNoSky = true - the default MC behavior is that we would return 128 in that case. Also undid a previous change to EventHookContainer - players that die in pockets will respawn in Limbo, again.
