Add trunkver: Versioning scheme for continuously delivered software

TrunkVer is a versioning scheme for continuously-delivered, trunk-based
applications and systems that don't follow a release scheme.

It is a syntax-compatible drop-in replacement for SemVer and replaces
the version with meaningful meta data, telling you at a glance what the
artifact is, when it was built and where you may find the build log.
