Enhancement to the version number generated for released artifacts

- Currently the released artifacts are in the form of:
 v<year><month><day><hour><min><second>_<shorttag>

The short tag was calculated from the baseforrelease branch after
applying the patches, that maybe contained in
patches/<branch>/<project> but that means we will not be able to
correlate the revision with the true base from which we released, so
inserting a baseforrelease_initial branch that is essentially the
pointer at the branch we created a release from.
