chore(build): changing server version to follow SemVer

We talked about this last week. If we change the versioning to 'minor' SemVer then we will be able to introduce hot-fix patch versions. 
Another idea is to maybe use "0.1.0" as the release version for the next train? 

@gene1wood warned that deployment may need to be adjusted to work with this change.
