Information Leak - I see rubble of destroyed buildings

[elexis]

You can see if enemy buildings are destroyed through the fog of war:

Reproduce:

1. Open developer overlay
2. Delete CC
3. Change perspective to enemy

For both explored and unexplored buildings you can see the rubble.

#3179 claims to fix this, but it doesn't (completely?). It works for units but not for buildings.

The commit intends to work for buildings though, see the change in the structures template and IRC on the day it was committed:

(11:38:02) elexis: does it work for structures too?
(11:38:11) Itms: yes, it's the same

By hosting a game with a second player attached, you can even faster change to the enemy perspective. It becomes apparent that the building doesn't fall anymore, but still the rubble is spawned and visible in fog.
