Fix velocity calculation location issue with primitive airfoils

Clientside optimizations, better lift/drag vector display

Lift/drag vector display is now scaled by the square root of its length rather than its length directly, no more extremely long vector lines

Allow P2M entities to have fin applied

Further primitive airfoil improvements - now accounts for the control surface setting properly

Better primitive airfoil support - now calculates the surface area and aspect ratio based on the primitive's settings rather than its bounding box

Fix drag removal/damping removal not being applied on physobj change

Clean up hud code, remove unnecessary title from tool menu, fix localization not loading

Make low pass filter optional, disabled by default

Low pass filter on lift/drag to dampen oscillations on light vehicles

Fix player fin count not decrementing when removing fins
