Title: Remove Turret and PVecFloat cruft.

These changes convert contrails / aircraft smoke / rotors / spinners / husk particles to world coordinates, and then removes the old Turret and PVecFloat types.

The only potentially controversial change is husks, where I have changed the throw logic to use a simple cubic ease instead of trying to emulate real physics.
