GitLab

This keeps a record of which commits each version of the Chrome Cleanup
Tool is built with. Currently this information is stored in tags on the
internal repo, but this approach won't work when the tool is built from
the public repo.

Goes with commit http://shortn/_zVs7MpRCuC in the internal repo that
stores the commit hashes in the protobuf.
