More wing/control surface options

First off, we need a way to attach things to wings, like pylons or procedurally place attachment points underneath or on top. But more importantly, there aren't good ways to have flap, trims or airbrakes. I could set a control surface to be controlled by a slider action, but then they don't fold to the same side as you'd want to adjust pitch. We need a way to not only reverse control direction on them but also invert on mirror. Also, there should be a type of surface which folds to both sides at the same time, increasing drag instead of changing angle of attack, so we can implement air brakes. Other military-style airbrake parts would be cool too, but the conventional wing surface brakes are more important.
