v0.1.1

Fixed

• newgit --version reported (unknown) instead of the commit for every
  binary installed from crates.io. The build stamp was derived by running
  git rev-parse, but a published .crate tarball ships no .git, so the
  stamp only ever worked when building from a clone — the one case where you
  can already see the commit. It now reads the sha1 that cargo publish
  records in .cargo_vcs_info.json, falling back to git for repo builds.
  A tarball packaged with --allow-dirty gets the same -dirty suffix a
  dirty clone does.
