[fix] change version inc to tags

Currently we use commit count to track versions. If we fork a repo the commit count is retained so the fork cannot have a new version

If we ie the latest tag v1,0.1 then we can inc this to v1.0.2. Tags are not copied with forks. We can also implement algorithm to reset lower version numbers if the user increments 1.1.x or 2.3.x in the config file.
