[LUA] Faction Change

Well, I've recently decided to try out LUA and make an NPC that allows a faction change. I've scripted it, however I'm not 100% sure if it works yet.

Short explination...

You have an NPC that allows a faction change to 1 of 4 pre-designated factions. You can change what factions are available, and what display ID's you can pick for each faction. Say you pick Horde, and your currently alliance, it'll give you the option of a list of Displays you'd like to be used for that factions. It also makes the other factions on the list change to "At War" so you can have new factions PvP'ing (But ofc, the factions are already In-game, like Argent Dawn etc)

Like i said, not sure if it works yet, would be nice if someone could test and report back with any errors for me to fix.
