Stamp the git tag or short commit in a plain docker build (closes #67)

.dockerignore now sends .git, without .git/config, which can hold a
credential. The build stage takes the VERSION build argument when one
is given, otherwise git describe --tags --always of that .git, and
fails if the context carries .git and still yields no version. A plain
docker build . used to stamp dev.
