Move advanced types into sections

[crutchcorn]

I personally feel that advanced types page is getting a little long and difficult to maintain or read through. I have more than a few parts I'd like to add to advanced types (conditionals are a doozy to get done and document all the catches/etc). Even as a reader, I always find it hard to tell if something is in the handbook or not and how to find it because of how long the advanced types page is
