Updated to latest Pixi build (can do away with our own local patch now).

Group.sendToBottom(child) is the handy opposite of Group.bringToTop()
Group.moveUp(child) will move a child up the display list, swapping with the child above it.
Group.moveDown(child) will move a child down the display list, swapping with the child below it.
