Doomsday Engine

When I make a wind sector that affects only objects
touching the floor, it's buggy.

Reproduction of the bug:

Sector 1 floor height is 64. Sector 2 floor height is 0.
Sector 2 has a special xg effect:

Sector Type {
ID = 7002;
Comment = "Floor move MEDIUM SPEED";
Flags = "stf_floorwind stf_windother stf_windplayer
stf_windmonster";
Floor texmove angle = 270;
Floor texmove speed = 1;
Wind angle = 270;
Wind speed = 0.5;
}

Player is in the sector 1. Player walks to the edge of
these two sectors. Whoaa! Wind strikes player and he
moves south.

I think that shouldn't happen.

The bug is in the XSTrav_Wind. The parts where there is
used mo->floorz(and possibly mo->ceilingz) are buggy.
If they're replaced with mo->subsector->sector-

floorheight and mo->subsector->sector->ceilingheight,

the wind works ok. No weird wind in the edges after that.
