Subject: - Removed the "history"-field from the SQL table "users" and added  
 this information to the "users"-field in both nodes and comments.   This
 database/table change reduces the number of SQL queries and   makes Drupal
 scale better where a lot of voting/moderation takes   place.  Last but not
 least it can be considered a new and better   foundation for future
 moderation metrics / algorithms.  In other   words: it is plain better.

    --> oops, all voting/moderation results will be lost!
    --> requires database update, see "2.00-to-x.xx.sql"!

- Updated database/database.mysql
