Identify all accesses to the Primary System Area 

Whenever a field was added to the end of the Primary System Area (PSA)
record, the offsets of all other fields would change. When reversing NK
version 02.27, I noticed that 32 bytes had been added to the end of the
PSA between 02.27 and 02.28. To build a byte-perfect 02.27, all
references to PSA fields must therefore use the record definition in
NKPublic.s instead of a numeric offset.

In this commit, all PSA references are identified by field name (_FFF if
the field has not yet been reversed).
