	* app/widgets/gimpdock.[ch]: added new pure virtual function
	GimpDock::setup() which configures a dock like a passed template
	dock.

	* app/widgets/gimpimagedock.c: implement it and set
	"show_image_menu" and "auto_follow_active" accordingly.

	* app/widgets/gimpdockable.c (gimp_dockable_detach): call
	gimp_dock_setup() to configure the new dock like the old one.
	Removed inclusion if "gimpimagedock.h".

	* app/gui/dialogs-commands.c: minor code cleanups.
