[Utils/FbxImporter] Fixed FBX loading

- FBX has Z-up coordinates; the recovered properties have been reordered to make them Y-up

- Failing to import textures catches the produced exception & outputs an error

- The FBX objects are now destroyed at the end
  - Not sure if this is actually required, but it won't hurt not having to think about it later
