* fix typo
* Handing buildifier exit status better.
buildifier started reporting an error for lint issue, update the script
to not stop because of that.
- Move install into a stand alone script to expand it.
- Support installing the latest bazel release.
- Move the script step into a stand along script to expand it.
- Support doing a build or running buildifier.
- Update the config to:
- Use the latest bazel release and head for tests (won't have
to update the config with each bazel release).
- Add a buildifer test to ensure the files are good.
