This rolls all "create missing" handling into BuildConfig, and moves the
build-dir option from the "book" table to the "build" table. Some
documentation cleanup surrounding the build table is also updated.
- removing need to explicitly use `Path::new` all over the place
- removed warnings from doctests (normally invisible unless `cargo test -- --nocapture`)
- no doctests are norun/ignore now
- updated docs both in book-example and in docs not to refer to nonexisting API's
As `theme` dir is no longer under `src`. Updates to "theme" did not
trigger book rebuild.
Also fixed misleading docs about `theme` dir being located in `src`
This fixes a broken link on http://azerupi.github.io/mdBook/cli/init.html
The `..` is redundant because the document's base URI is set to
`path_to_root`. It breaks if the base URI is not at the server root.
