HouseSetup Rewrite

With my new InitialiseGrid function handling all the heavy lifting of setting up a proper game grid to work on, I had to turn my attention to the HouseSetup function and completely rework all my formulas and algorithms to get a starting house built. This took me many hours of painstaking calculation, implementation, and trial-and-error, but I like the way this new code base works and it will allow me much greater flexibility moving forward. It will also make it much easier to build new tools and layers on top of this code, which was the ultimate goal of going back three steps in order to get back to where I was already at.
