	* app/core/gimpchannel.[ch]: changed gimp_channel_get_color() to
	not return the color but take a second GimpRGB* parameter like all
	other _get_color() functions. Reordered some functions to make
	more sense, added some g_return_if_fail().

	* app/core/gimppalette.[ch]: added gimp_palette_[set|get]_n_columns()

	* app/gui/menus.c: added a "<PaletteEditor>" item factory.

	* app/gui/Makefile.am
	* app/gui/palette-editor-commands.[ch]: callbacks for the factory.

	* app/widgets/gimppaletteeditor.[ch]: removed the menu stuff here,
	added a spinbutton to adjust the number of columns.

	* app/gui/gradient-editor-commands.c: removed usage of "the_gimp".

	* app/widgets/gimpgradienteditor.c: minor cleanup.

	* app/widgets/gimpbrusheditor.h
	* app/widgets/gimpgradienteditor.h
	* app/widgets/gimppaletteeditor.h: forgot to declare the _get_type()
	functions publically.
