Need to mimic a evac function for spawns

Sorta not needed as we have SetPosition. However, npc's would tend to wander back to its spawn point so added a command to prevent this - ClearRunback(NPC). You can use the following to test (loc below is for GMHALL).

function hailed(NPC, Spawn)

FaceTarget(NPC, Spawn)

Say(NPC,"Hell no! I'm out! -poof-")

ClearRunback(NPC)

SetPosition(NPC, 684.86, -35.96, 1531.88, 250.63)

end

NPC should now port to the location and stay there.
