#14 Crash when destroying building

[Kimmo Merikivi]

After some buildings are destroyed, game crashes and
you get debug message like this:

"src/unit/unit.cpp:920: Lost unit-darkness-wolf-jail(388)
Assertion failed at src/action/action_die.cpp:86:
unit->Type->TileWidth ==
unit->Type->CorpseType->TileWidth &&
unit->Type->TileHeight ==
unit->Type->CorpseType->TileHeight"

Maybe this is because of "corpse"-size and maybe this
is only in wolf jail but it is better to check all
buildings..
