Use getRemainingTileCount (pending + readyQueue) and processAllReadyTiles
to prevent loading screen from exiting before tiles are finalized. Auto-select
realm and character when only one is available.
Fix movement packets to include packed player GUID prefix so the server
tracks position. Fix inventory money display being clipped by child panels.
Add Back and Delete Character buttons to character selection screen with
two-step delete confirmation.

In single-player mode, auth screen now goes to character creation before
entering the world. In online mode, a "Create Character" button on the
character selection screen sends CMSG_CHAR_CREATE to the server. Includes
WoW 3.3.5a race/class combo validation and appearance range limits.
