Title: wp-cli 0.4.0

Upgrade wp-cli to version 0.4.0.
Adjust the location of the source files because the directory
structure has changed. Add a `skip_clean` so that an empty
directory remains after install, because it helps identify
in the formula a directory that should not be missing.
Asking upstream how to get this directory populated.
At the moment, only the HEAD works. The stable 0.4.0 and
a tarball of the current commit do not work because the
`skip_clean` directory, `php-cli-tools` is supposed to be
populated from a git submodule, but that doesn't happen in
tarballs. It only happens in a git clone of HEAD. Also
asking GitHub help why or how to work around this. Don't
pull this new formula until this is resolved.
