Building Land Classes

The building ruins system introduced in Armed Assault is quite different from the one in Operation Flashpoint. In Operation Flashpoint, a destroyed building saw its vertices moved, twisting its 3D model as well as its collision LOD - making this a very cheap but improvable system.

In Armed Assault, the original building moves under the terrain to simulate collapsing; the damage also changes from 1 back to 0.
Destroyed Buildings that used the DestructEngine type will vaporise (dissappear) unless a ruins model is associated with them.

The class needs to be called Land_xxx for ruins to work.

the class needs to be called Land_xxx for building animations to work in Armed Assault; this is not true for later titles.
