JDF-250 / JDF-253 - Sync Archetypes with Quickstarts

This Pull Request has 3 modifications/commits

1) Remove the Blank Archetype - There's no need to keep the Archetypes on gitrepo since it's generated with release.sh script

2) Added pom.xml config that to use qstools:archetypeSync goal. The main point is that a Archetype could be synched with a branch/tag/commit - The idea is that the archetypes should use a quickstarts .Final tag on each JDF release.

```xml

3) The synchronization it self. I tested it but I would like that you test it too before I merge this PR.
