Versioning

TwometerVR uses sematic versioning, that means MAJOR.MINOR.PATCH (e.g. 2.4.9)

Prior to version 2, Some subprojects had wrong or unassigned version numbers. Now, every subproject has the same MAJOR version. However, each one may have different MINOR and PATCH parts.

For consistency's sake, the version 2 rewrite reset the version of all subprojects back to 2.0.0
