The command is predefined in NaviServer; if not available, a comatibility version is added. This change also mitigates a potential memory-leak problem in nsv_dict with certain versions of NaviServer which might lead on busy sites to problems.
- added handling of cachingmode "none" - added implementation via "nsv_dict" (cluster aware) - execute parameter callbacks cluster-wide - version number bumped to 5.10.1d4
