	Added an API for image colormap manupulation and made colormap
	changes undoable (fixes bug #25963).

	* app/core/Makefile.am
	* app/core/gimpimage-colormap.[ch]: new files implementing
	colormap getters/setters. The setters push undos using the
	new function below.

	* app/core/core-enums.[ch]: added GIMP_UNDO_IMAGE_COLORMAP.

	* app/core/gimpimage-undo-push.[ch]: added
	gimp_image_undo_push_image_colormap(). Use GimpItemUndo even more
	often. Cleanup.

	* app/core/gimpimage.[ch]: removed gimp_image_get_colormap() here.

	* app/core/gimpimage-convert.c
	* app/gui/colormap-editor-commands.c
	* app/widgets/gimpcolormapeditor.c
	* app/widgets/gimptoolbox.c
	* tools/pdbgen/pdb/image.pdb: use the new API.

	* app/pdb/image_cmds.c: regenerated.

	* plug-ins/common/vinvert.c: removed the comment about the bug,
	cosmetic cleanup.

	Unrelated:

	* app/gui/splash.c: added a frame around the splash. Please eek
	if it doesn't please you.
