* app/gimpimage.c: Factored out common code from
gimp_image_{raise,lower}_layer and
gimp_image_{raise_layer_to_top,lower_layer_to_bottom}. They
now call gimp_image_position_layer() to do the real work.
* app/gimpimage.h: gimp_image_position_layer() takes extra arg to
tell whether an undo should be pushed.
* app/layers_dialog.c: reposition layer with undo.
* app/undo.c: new undo type for layer reposition. Layer rename
shouldn't dirty and clean the image twice!
* app/undo.h: prototype for undo_push_layer_reposition().
* app/undo_types.h: LAYER_REPOSITION_UNDO type.
