registry : cleanup of queries (indicators & UI, Phase / subproject)
* improved NXQL_WHERE_NO_PROXY & cleaned up other NXQL_ and their uses
* replaced getWorkingCopy() (wrong !) by getSourceDocument()
* improved RepositoryManagementListener (skips proxies of versions, was causing SQLDocumentVersion$VersionNotModifiableException)
* cleaned up SubprojectServiceImpl.getXXX (no more using name or path...) and their uses
* updated UI (removed wrong IS_NOT_VERSIONED, don't get tagged services by path) & tests
* cleaned up indicators, still TODO : ServiceConsumption, SoftwareComponent
