  Fix Renderer generator script.
  
  This script breaks peridocially because we don't have automated tests
  for it. Split the FBO attachment object class into its own file, and
  also fix a couple other small snags that prevented the script from
  running.
  
  This will facilitate generating Vulkan renderer stubs.
