	* app/widgets/widgets-types.h
	* app/widgets/gimpsessioninfo.[ch]: added new struct
	GimpSessionInfoAux which contains "gchar *name" and "gchar *value".
	Changed sessionrc "aux-info" format again to be really extendable
	this time. Also breaks everybody's sessionrc again.

	* app/widgets/gimpimagedock.c
	* etc/sessionrc: changed accordingly.

	Implemented the stuff suggested in bug #122964. Fixes bug #122964
	and bug #52206:

	* app/widgets/gimpdataeditor.[ch]: replaced the "Gimp" member by a
	"GimpDataFactory" and changed gimp_data_editor_construct()
	accordingly. Implement GimpDockedInterface::set_aux_info() and
	get_aux_info() and remember the currently edited data across
	sessions.

	* app/gui/gradient-editor-commands.c
	* app/gui/gradient-editor-menu.c
	* app/widgets/gimpbrusheditor.c
	* app/widgets/gimpgradienteditor.c
	* app/widgets/gimppaletteeditor.c: changed accordingly.

	* app/widgets/gimpcoloreditor.c: remember the active color
	selector across sessions.
