Prep for 2.3:
 - update DLL version number
 - add files required for 2.3 (no changes to modules though)
 - restructure build of pgen.exe

NOTE:  As I don't have the VACPP compiler, these changes are untested.
Apart from slightly re-ordering some file lists, and matching file name
casing, I believe these changes are the minimum necessary to build 2.3
with VACPP.
