Bukkit

Initial Release: /spt setspawn

Checks if the player is in a portal on join, if so add them to a list if they aren't in the list, when they quit, they check if they're in a portal and in that first list, if so, add them to a second list, if they join again and are in both lists, they get teleported to the spawn point that's set.
