package.json drops its version field and is private (closes #158)

package.json said version 1.0.0, a release that has not been made.
Nothing reads the field, and the package is never published; the git
tag is the one version, which the image and make build take from
git describe --tags. The field is gone, so there is nothing to keep in
step with tags, and the package is marked "private": true. That also
ends the yarn warning about workspaces in a package that is not
private, which make bootstrap printed.
