* libgimpthumb/gimpthumb-utils.[ch]
* libgimpthumb/gimpthumbnail.[ch]
* libgimpthumb/gimpthumb.def: added missing API, mainly for deleting
thumbnails.
* app/core/gimpimagefile.[ch]: when saving a thumbnail, delete a
failure thumbnail if one exists. Unless the thumbnail was created
explicitely, remove all other thumbnails for this image.
* app/actions/documents-commands.c: changed accordingly.
* app/file/file-open.c: only save a thumbnail if there isn't a
valid thumbnail already.
* app/widgets/gimpthumbbox.c: before attempting to create a new
thumbnail, check if there's an uptodate failure thumbnail.
