Prevent JavaApiVersionInfo change on build

Let's move build number outside of JavaApiVersionInfo class so that it is not changed on build. Build number should be put into another file, like MANIFEST.MD or utplsq-api.version. Changing sources on compilation is never a good idea.

Any improvement on that is absolutely appreciated. Adding VersionInfo in the way it's done was just a quick-win compared to having no VersionInfo at all.
