	* app/core/gimppaintinfo.[ch]: derive it from GimpViewable.

	* app/core/gimptoolinfo.c (gimp_tool_info_new): set the
	paint_info's stock_id from the tool_info's stock_id.

	* app/widgets/widgets-types.h: resurrected GimpItemStrokeFunc.

	* app/widgets/gimpvectorstreeview.[ch]: added a item_stroke_func
	pointer and use it instead of implementing stroking here.

	* app/gui/vectors-commands.[ch]: added vectors_stroke_vectors()
	which has the signature of a GimpItemStrokeFunc.

	* app/gui/dialogs-constructors.c: use it for the paths dialog.

	* app/gui/stroke-dialog.[ch]: extended to handle both libart and
	GimpPaintCore stroking. Use a GimpContainerMenu view on the
	gimp->paint_info_list container to select the paint core to use.
