Clear Sky Invulnerable Trader

with the last version. A problem with the meshes made all npc's invulnerable. I tested this by going on a killing spree. The result being, all npc's except traders, were promptly put out of their misery. So this is a fixed version. Thanks for downloading my mods, I appreciate the feedback for letting me know my mods are good or that I messed up and need to fix an error.
This makes most of the traders invulnerable to dying. When you sell a trader lots of your loot, he is prone to dying, probably because of shock at paying out all that money. Anyway, fixed a MAJOR bug
