A_FogMove

Does nothing if the calling actor's args[4] field is null. Otherwise, moves it in its current direction, at a speed determined by its args[0] field, and use args[3] as a countdown, decrementing it at each call and putting the calling actor in its death state once it goes below 0. Every four calls, the calling actor's Z-position is slightly adjusted as if it had the FLOATBOB flag, its special2 field is used to keep track of the floatbob sequence.
