Images: changes to avoid losing new images that have not been saved

Browse Source 
The basic idea is that such new images will be packed into the .blend file
when saving all modified images from the quit dialog. To make this workflow
nicer a number of changes were made to how this type of packed image is
handled.

* "Save Modified Images" now packs generated images into the .blend file.
* "Save As" for packed images now automatically unpacks the image, so that
  it's easy to save automatically packed images. "Save Copy" keeps it packed.
* "Save" for packed images now re-saves the image into the .blend file, so
  that it's effectively the equivalent of "Save" for non-packed images.
* Empty image filepaths are no longer remapped when saving the .blend file.
  Previously it would become e.g. "//../../" which makes no sense for generated
  images with no filepath yet.
* Hide unpack button and filepath for such packed images with no filepath.
  Unpacking does not work in a predictable way without a filepath, better
  to just "Save As".
