Version string now dynamically generated 

This was motivated by Git itself, which uses `git describe` output to
generate the version number relative to the last tag. The format of it fits
fairly cleanly into the existing ease.js versioning scheme, but the m4
macro had to modified slightly to handle additional dashes.
