Made the building menu more logical. Rows according to tech tree.
power / refinery / silos 0/10/15
barracks / outpost / starport 20/30/40
light factory / heavy factory / repair bay 50/60/70
high-tech factory / ix tech center / palace 80/90/100
If you want to move silos to the Defense queue, then I would re-arrange it slightly.
