fix for long standing problem with blender 2.5x py api.

Removing data then accessing would allow invalid memory access and often crash.

Example:
  import bpy
  image = bpy.data.images.new(name="a", width=5, height=5)
  bpy.data.images.remove(image)
  print(image.name)

Now access to the removed data raises an error:
  ReferenceError: StructRNA of type Image has been removed

This is the same level of error checking that was done in blender 2.4x but was made difficult by RNA functions not having access to the PyObject's.
