	* Makefile.am (SUBDIRS): added libgimpthumb.

	* libgimpthumb/gimpthumb-utils.c
	* libgimpthumb/gimpthumbnail.c: basic functionality is implemented
	and seems to be working.

	* app/Makefile.am: link the application against libgimpthumb.

	* app/core/core-types.h: include libgimpthumb/gimpthumb-types.h.

	* app/core/gimpimagefile.[ch]: removed thumbnail handling routines
	and use libgimpthumb instead. Fixes bug #127914.

	* app/gui/file-open-dialog.c
	* app/widgets/gimpdocumentview.c: changed accordingly.
