Core library migration

I've set up a Google Sheet to track progress of the Core library migration: https://docs.google.com/spreadsheets/d/ ... sp=sharing

It has a list of all Quest 5's Core.aslx functions, and their status - which ones have been converted, which ones will/won't be, and also their priority.

Great! Things like ChangePOV should be almost trivial once the object model (and overall code framework) is in place.
