CENTAG 78 still ok under latest version

[Juramentado]

I resurrected an old 1.5 campaign CENTAG 78. Still works and has aged nicely under the latest game engine changes. Some minor oddities, ZSU-23/4 shows up as a mobile SAM launcher, but nothing show stopping. I've been looking for more Cold War stuff, esp., Fulda Gap and Cavalry type actions, and it's great this one stills works.
