Vehicle destruction

Finally finished with the vehicle destruction system today. It's quite complex: unlike most games, vehicles have many different systems, which have specific effects when they get destroyed.
Crew is also vulnerable while inside the vehicle, and may get injured or killed even before it's severely damaged.
The following video is a demonstration of the damage system, applied to the Type 63 tank.

This is what happens internally during the video:

- The hit @0:05 destroys the driver's station, killing the driver and forcing the vehicle to stop
- Next hit destroys the vehicle's left track, immobilizing it
- Crew starts bailing out @0:08 (you can see the top hatch open though the fire)
- Hit @0:21 destroys the right track
- Hit @0:22 is a critical impact on the vehicle's ammunition stores, igniting them and causing high-speed flames to erupt from the sides of the turret. Everyone left inside dies.
- Extreme pressure inside the vehicle causes a secondary explosion @0:42, detaching the turret and hurling it through the air.
Another video showing destruction of other types of vehicles is coming soon.
