Merge pull request #38 from armm77/master

* Correction to create horde vehicles.
Wintergrasp: The player and vehicle teleports will now work again.
Wintergrasp: The battlefield map display will now be shown to all players in world. Also the spirit guides will work (need info on what opcodes are sent to do them blizzlike).
No need to send the map worldstate when the player moves from one zone to another.
