Added support so that during the loading of a xml link list, it checks if a linked hypergrid region's real location is within 4096,4096 map spaces of its "local" location. If it is outside of that range ( so it wouldn't be possible to teleport to it) then it ignores it and doesn't create a link.

See the hypergrid wiki page for more details.
