c172p updates
removed action-sim.nas + nose gear scissor animation computation now via interpolation xml + main gear rotation due to compression now via interpolation xml + moved NAV0 and NAV1 needle deflection filters to pseudo-autopilot xml + moved pannel and instrument lights control to light.nas + the remaining tank setlisteners are now in tank.nas pa24-250 updates + landing light animation now modeled after pa22 landing lights
