AME Taxi Map Tools - Layout files

Core/Design.lua is the active new AME Dark Layout.
Core/Design.luaold is the old legacy layout, disabled because the .toc only loads Core/Design.lua.

To switch back later:
1. Rename Core/Design.lua to something like Core/Design_AMEDark.lua
2. Rename Core/Design.luaold to Core/Design.lua
3. Reload the addon/game.
