Adding versions to all relations (including implicit relations such as inheritance or main implem of composite)
Added new constants and prefixes (mostly useful for OBR capability generation)
Added new profile : local to enable build of the apam maven plugin (defintion of packaging bundle but without mavan-bundle-plugin)
modifications of obrman tests case services to check if the new apam-maven-plugin works properly with the private repositories
Apam maven plugin is now able to check OBR repositories to verify that an apam component is complete
