[HOT] Squared buildings

[Jo]

Performing a search for all buildings with 4 nodes, this might be an
acceptable solution. There might be other problems with those buildings,
but it would be relatively easy to perform the search once more and then
let all of the buildings pass the revue using the todo plugin.

I might make a screencast to demo this later today.
