Basically, blender adds a few metadata fields to images when we render an image. Those metadata can now be viewed in the image editor. Also, made sure metadata are available when we write imbufs to disc with "Save As". There may be more cases here that need fixing, but this means that loading an image with metadata will now properly preserve them in blender.
