Add orchestrator code for equality functions for Z60/Natural language & Z31/Monolingual stringset
The built-in equality functions are Z862 and Z832
Also, slight re-factoring of some code into a new function: getNormalizedPersistentZObjectFromFile
Requires pull-through of function-schemata!340 (merged) and function-schemata!341 (merged)
