Tie PlayerList#moveToWorld safety to existing config

Also renames patch file to better express what it's doing.

It is presumed that those using this config option intend for
suffocation checks to be disabled in all instances. In doing so, they
inherently assume the advantages and issues associated with removing
said safety check.

If the community expresses a desire for more specific options regarding
the handling of this safety feature, we can investigate providing them.

Fixes GH-1149

+People are able to abuse the way Bukkit handles teleportation across worlds since it provides a built in teleportation
+safety check.
 
-To abuse the safety check, players are required to get into a location deemed unsafe by Bukkit e.g. be within a chest or door block. While they are in this block, they accept a teleport request from a player within a different world. Once the player teleports, Minecraft will recursively search upwards for a safe location, this could eventually land within a player's skybase.

-The wanted destination was on top of the emerald block however the player ended on top of the diamond block. This only is the case if the player is teleporting between worlds.
