while it still remains a good idea to port as many NULL compares and assignments over to nullPtr as feasable, we do still need to sort out how to better support scripted empty, false, and zero assigns for things like objectIDs. this means we'll need to both fully convert the backend of the parser to support that kind of thing, but also alter most if not all exisiting NULLs. up to and including things like SAFE_DELETE. while that's certainly feasable, given there's aproximatel 400 nullptr assigns/checks prior to this commit, and roughly 1800 of the prior, if it terminates in a script call and not an aip one direct, we'll be dialing that back until such time as fork fully fopcused on converting and resolving any lingering mismatches is completed.
