Add a check to town gen code to see where the structures are and if the bounding boxes would overlap.

yup, im seeing this a lot now in testing - maybe 10% of towns overrun a "normal" structure spawn in this way.

Interestingly they never seem to overrun RUINS mod or Vanilla structures - so maybe the validation code that's used for them should also be applicable to the normal AW structures?

Fixed in the latest release
