[KPhotoAlbum] Speeding up annotation

[Robert Krawitz]

Here are the two patches for annotation dialog:

- patch-annotation-selection.patch improves the selection
  regeneration.

- patch-annotation-2.patch improves the recomputation of the options,
  by improving the computation of the selected/unselected sets, and by
  only applying changes rather than reapplying everything.

Combined, it goes from taking a few minutes to apply a change to
30,000 images to taking a second or so.
