Requested new features for SE:IV

[gregebowman]

I just thought of an idea I'd like to see incorporated in SEV. Have it where when you are trying to build a facility on your planet, have it where the facilities that are already on that planet are blacked out, or at least earmarked somehow, so that you know that you already have such a facility on this planet. Some facilities you could have multiple times on the same planet, but others can only be on the planet once. Looking at the production screen, you have no idea of what you got on that planet, unless you want to get out and then check out the facilities on the planet detail screen. It would save me a step or two if I could see on the production screen that I already have facility X on the planet.
