Bit of an experiment with giving flakes a bit more depth. Might need to be theme flagged, or theme flakes reworked on some themes. Looks neat in stereo. Also finally use an array for the layers

foreach(dir "Fonts" "Forts" "Graphics" "Locale" "Maps" "Music" "Sounds" "Themes" "Missions" "Names" "misc" "Scripts")
  add_subdirectory(${dir})
endforeach(dir)
