-Added texture names array to generated script. These files all
specifically loaded rather than looping through a particular folder.
-Renamed some functions for better clarity
- Added Fungus Editor Resources folder for editor textures (these
should no longer get included in builds)
- Added pro skin icons in Fungus Editor Resources/Icons/Pro
- All editor textures should now be accessible as properties in
FungusEditorResources. If the textures change, use Tools -> Fungus ->
Utilities -> UpdateEditorResourcesScript to automatically update this
