Streamline library version reporting

[bschulz1701]

Try to link the version given in the library.properties file with the library version reported by LibVersion

I would suggest git hooks:

You could search for the most up-to-date tag and insert the number into library.properties on commit.
I do something similar with a custom script to write my python packages to PyPI tagged with their appropriate version(s), but it isn't integrated with the git tag (as I've suggested here)... for no good reason.
