    org-display-inline-remove-overlay: Do better job clearing images from cache
    
    * lisp/org.el (org-display-inline-remove-overlay): Force remove
    overlay images from Emacs image cache when un-displaying inline image
    overlays.  This change should: (1) slightly improve Emacs memory usage
    when the number of inline images is large; (2) Clear images from cache
    every time Emacs removes the overlay for any
    reason.  (`org-display-inline-remove-overlay' is used in
    overlay 'modification-hooks.)
