[CF List] Reliable saving of players/unique-items

[Jacek Konieczny]

Hi,

I have just lost my apartments again, because of full filesystem (BTW it
was filled by crashed crossfire). I have never lost the player the same
way, but if player files are created the same way as unique-items file 
it can always happen.

Maybe those files should be created more reliably. Eg. by writting
file.new first, and only if it succeeds the file would be renamed to
proper name. It can "save some lives".

Greets,
        Jacek
