	* app/actions/gradient-editor-actions.c
	* app/actions/gradient-editor-commands.[ch]: added actions and
	callbacks to select a gradient segment's left and right color
	type. Handle FG/BG color correctly in a few places. Use
	GimpDataEditor's context instead of the user context.

	* menus/gradient-editor-menu.xml: added the actions to the menu.

	Cleanup:

	* app/actions/palette-editor-actions.c
	* app/actions/palette-editor-commands.c: use GimpDataEditor's
	context instead of the user context.

	* app/actions/brush-editor-actions.c: remove unused context
	variable.
