John "Elwin" Edwards 2b6d8bcb77 Advanced Rogue 7: ignore file locations in the save file when restoring. 
The variables file_name, score_file, and home are no longer overwritten
with the values stored in the save file.  Those values could be
inaccurate if the files have been moved or configuration has changed.
