giants accidentally break doors when training

[ghost]

Creatures in the training room they sometimes go to the edge of the room and hit on the wall as part of their training routine.

Giants when they attack near a door as part of their training routine they will actually damage it and eventually destroy it.

I think Giants have a weird interaction with DESTROY_WALLS annoyed behaviour which somehow makes them accidentally break doors when training. Their attacks have some form of flag on them that is considered actual attack on walls/door. They don't seem to break walls while training though. But I remember when they get annoyed they do break doors and walls.

This bug is pretty funny and I have a feeling it was intentionally left in the game. I remember this from vanilla DK and it seems KeeperFX has it too.

It's not just giants, all creatures have this. Giants just do massive amounts of damage so it's easy to notice.

However, this issue is already raised: See #323
