* Added option to shelve the build result to the workspace of a specific user (skipping the submit)
* Created a generic WorldPartitionBuilder BuildGraph command that will allow this kind of operation on any WP builder
* Added a P4.UpdateChange() overload that takes a client (workspace) argument
* Renamed the HLOD_Submit step to HLOD_Finalize, as it can either: gather files from multiple builders locally without submitting / submit the result / shelve the result
