John Updates 12/28

Minor notes: I updated the CR90 article with some basic bits about the Ion upgrades, and I updated very barely the Squadrons Encyclopedia 1 article with terminology and such in there.  More to come on that all, of course.  But for now, hey look, updates!

I also hit the MC75 (some Caitken and Shollan improvements and shamelessly stealing JJ's Vassal World Cup MC75 build), and I added in C&S to the AF and the MC30 articles
