Comment 24 for bug 895346

Current problems:
- Ignores Iron Curtain
- Slaves of Slave Miners do not change sides. They should switch sides to the killer like with other weapons.
- Same with spawning units. The spawns should die.
- Special house Slave Miners start harvesting ore
- If a unit is mind controlled, it is freed. If a unit is a mind controller with captured units, they are neither freed nor do they change sides.
- Units with killed drivers still drive around and do stuff (when in teams?).
- Shooting on a Special house unit can cause it to move a little to dodge fire.
- Special house is allied to everyone. Infantry can enter transports/operated units and you won't get them back.
