System/Planet Facility Stacking

[douglas]

In most cases one planet facility and one system facility stack with each other, but extras of either have no effect. Notable exceptions are planet-wide value and condition improvement facilities, and planet-wide happiness modifiers in mods that have them. These facilities stack infinitely. Also, sector-based training facilities stack if they are in the same sector but not on the same planet. This means planets with lots of moons are the best places to put training centers.
