Goonheim feat calc fixed

Well, I was just about to sit down and re-do all the feat builds in the calc since recently goonheim went bonkers, BUT turns out they were a step ahead of me and have made their calc backwards compatible :) So, just letting you all know the links should be working fine. If you find any that still seem to be wrong. I'll be working on some of the bits I mentioned below as the week goes on; started training at the new job today, though, so it might take me a day or two.
