2000-05-27  Michael Natterer  <mitch@gimp.org>

	Libgimp cleanup part II (with a little help from Yosh
	who moved the CVS files).

	* libgimp/Makefile.am
	* libgimp/gimpchannel_pdb.c
	* libgimp/gimpdisplay_pdb.c
	* libgimp/gimpdrawable_pdb.c
	* libgimp/gimpgradient_pdb.c
	* libgimp/gimphelp_pdb.c
	* libgimp/gimpimage_pdb.c
	* libgimp/gimplayer_pdb.c
	* libgimp/gimppalette_pdb.c
	* libgimp/gimpparasite_pdb.c
	* libgimp/gimpselection_pdb.c
	* libgimp/gimpunit_pdb.c: new names of all files which contain
	PDB wrappers.

	* modules/Makefile.am
	* libgimp/gimpcolordisplay.h
	* libgimp/gimpcolorselector.h
	* modules/gimpmodregister.[ch]: renamed.

	* libgimp/gimpparasiteF.h
	* libgimp/gimpparasiteP.h: removed because gimp.h had to include
	the private header anyway.

	* app/color_notebook.c
	* app/color_select.c
	* app/gdisplay_color.[ch]
	* app/gdisplay_color_ui.c
	* app/gimpbrushpipe.c
