Fix empdump not to grow game state files with fixed size

Browse source 
empdump -i now complains about extra rows instead of silently growing
the file to a size the server will reject.  Affects tables sector,
nation, realms, game.

Bonus fix: better error message on I/O error or insufficient memory.
