CGTB version four

I hate hate hate working on this thing while I'm on vacation, but I knew what I was signing on for, years ago.

Edits have been pretty light, I'm about ~100 pages through them and they're going pretty fast. Unfortunately my ability to do research from here, where internet access is horrible, price and unreliable even where available, is pretty limited, so I've been unable to answer some re-re-research questions. We'll see what happens.
