Beta 4: Signs in front of escape doors

[RobSeegel]

I was able to duplicate this. I create a one-room mansion with an exit.

First with no sign: key does nothing - to be more accurate though, it's the action key - whatever it's set to. Mine is set to the ctrl key. The action key does nothing either.

Second with a sign in front of the exit door. Again did nothing for me since it is not my action key. did trigger the exit instead of the just the sign as I would have expected.
