The InputPlugin.sortGameObjects method was using the Camera Render List to determine the Game Object display list. This would exclude non-rendering objects, such as Game Objects with alpha set to zero, even if their Input alwaysEnable flag was set. This method now uses the Display List instead, which gives correct results for invisible 'always enabled' objects. Fix #5507
