Rollup merge of rust-lang#47753 - steveklabnik:update-book, r=alexcrichton

Update book

This PR does two things:

1. update the book to include rust-lang/book#1088
2. update to mdbook 0.1

Both of these things are big changes, so I want to land them now, well before the next branch, so we can kick the tires.

Putting this PR up so others can try and build and see if it reproduces for them.
