Add flaps: flappable tag, flap lever on the control node, flap physics (0.4.0)

Shift-right-click a block in improved_aerodynamics:flappable to make it a flap.
G/H step the node's flap lever UP/TAKEOFF/LANDING; flaps slew to the configured
angle, add lift and drag and raise the stall angle, and retract above a max speed.
