[CALC] Improve the handling of configuration settings. CORE-3085, CORE-8486

Browse source 
Configuration is read from WIN.INI under W32S/Win9x/Me and from the registry
for all NT platforms.

Although with INI file mapping the keys are still saved in the registry
even on NT, I added handling of different platforms for writing directly
the configuration in the right place.
