Add teleporter panel and server-compatible coordinate conversions

Browse source 
Teleporter panel (T key) lets the player teleport between Goldshire,
Stormwind Gate, Ironforge, and Westfall in single-player mode. Adds
serverToCanonical/canonicalToServer conversion at the network packet
boundary so positions are compatible with TrinityCore/MaNGOS/AzerothCore
emulator servers.
