Added a couple of Wiki pages

[Strategia_In_Ultima]

I've added the text in the Facilities article to the top of the Facilities category too. I've included the stub tag. If you want to expand the article proper or the cat description, well don't let me stop you; but let's confine the long stories about how facilities evolved from SE II to III to IV and all that to the article, and keep the cat description concise, shall we? I know of a wiki where some cat pages are "graced" by endless stories of in-depth information, and it's not that I have an aversion to it, but I think it'd be better to keep the cat pages clean
