Move scripts to their own dir (aptly named script)

Move scripts to their own directory.
Add `serve.sh` for serving locally (from internal build repo).

Rename:
- clean.sh -> script/clean.sh
- make.sh -> script/make.sh

Now you can type `make serve` to serve the guide locally.

$ make <TAB>
all    clean  guide  serve

Requirements are still included in the `serve.sh` file.
