Fixed structure build menus

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.
