[fpc-pascal] Configuration file handling

[Andrew Brunner]

I would not use INI if the systems are writing data.  While I've had 
plenty of success reading INI files in parallel - I seem to recall that 
the file is just streamed out without regard to which version is on 
disk.  I think the file is completely refreshed.

I recommend using a DBMS system of some sort for read/write ops in parallel.
