	* libgimpwidgets/gimpstock.c: added stock *items* (not only icons)
	for all tools so they can be used as action buttons.

	* app/tools/gimptransformtool.[ch]: added
	transform_tool->use_center so subclasses can switch on/off center
	detection/cursor_update . Added an oper_update() implementation
	and figure the current handle out there. Reordered button_press()
	so we don't need to call it recursively.

	* app/tools/gimpperspectivetool.c
	* app/tools/gimprotatetool.c
	* app/tools/gimpscaletool.c
	* app/tools/gimpsheartool.c: use the new stock items instead of
	_("Rotate") etc.

	* app/tools/gimpperspectivetool.c
	* app/tools/gimpscaletool.c: allow the whole thing being dragged
	around by handling the center separately.

	* app/tools/gimpdrawtool.c: gimp_draw_tool_on_handle(): need to
	use the radius, not the diameter to check if being over a
	GIMP_HANDLE_CIRCLE handle.
