	* app/widgets/gimppaletteeditor.[ch]
	* app/gui/palette-editor-commands.[ch]
	* app/gui/palette-editor-menu.c: started to clean up the palette
	editor: added buttons for all menu items and menu items for all
	buttons. Improved selected palette entry handling. Moved all code
	to gimppaletteeditor.c and call it from the menu callbacks.  Lots
	of cleanup (unfinished).
