Walk to the Desert Redux - 1.2.9

Several things have been updated, firstly all tilesheets have been updated to include some highway road signs pointing to Downtown Zuzu, courtesy of Harvz, special thanks to João シ for discovering a texture issue with the Starblue version of the Ghost Town tilesheet. All warps going into Walk to the Desert Redux are now LoadMap warps, this prevents the ability for NPC's to wander in aimlessly and going somewhere they shouldn't be going. Minor performance, asset and code enhancements.
